AFR recommends the use of .120\" thick-wall pushrods.\u003c\/li\u003e\n\u003cli\u003eAFR 227\/235cc Heads: Due to the \"60\/40\" stud and valve locations, shaft mount rockers are highly recommended, however if you're ONLY Drag Racing you can run a .050\" offset intake stud mount rocker with the AFR supplied guide plate (exhaust will use a standard rocker). Please note that with the .050\" offset rocker arms the roller tip of the stud mount rocker will not be perfectly centered and will not sit squarely on the valve causing increased side loading and wear. This option is not recommended for race\/endurance applications and\/or street engines that see a lot of miles.\u003c\/li\u003e\n\u003cli\u003eAFR LT-1 \/ LT-4 \/ Vortec Heads\/ Late Model TBI\/TPI Heads - Your factory accessory bolts and center bolt valve covers need to be shortened 3\/16\" or they will bottom out. These cylinder heads are machined for both center and perimeter bolt valve covers, please see your instructions to avoids oil leaks.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eGeneral Recommendations for AFR Cylinder Heads:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBar Codes - Please keep the bar code \u0026amp; paperwork shipped with your head, these contain all the specs for your heads when calling AFR.\u003c\/li\u003e\n\u003cli\u003eHigh Volume\/Pressure Oil Pumps - If you are using a high volume or high pressure oil pump it can submerge the valve seals in oil causing smoking or oil consumption. Your block manufacturer or engine builder can recommend oil restrictions to the top end\/valve train components.\u003c\/li\u003e\n\u003cli\u003ePushrods - Different length pushrods might be required, always check pushrod length. Check pushrod clearance with heads placed on the block before final assembly. Larger pushrods will not fit without clearancing and is not recommended since some areas are very thin. AFR recommends the use of .120\" thick-wall pushrods.\u003c\/li\u003e\n\u003cli\u003eMills - Flat or angle mills could affect flow numbers and might require a thicker intake gasket.\u003c\/li\u003e\n\u003cli\u003eStud Girdles - Due to many available factory OEM and aftermarket style\/variations your existing stud girdle may not fit (AFR heads require AFR Stud Girdles)\u003c\/li\u003e\n\u003cli\u003eBoosted\/Nitrous Applications - We strongly recommend considering Inconel exhaust valves and AFR's optional heavy duty intake valve for power adder applications. Since boosted or nitrous oxide applications accelerate RPM quickly, additional spring pressure is required. We strongly recommend upgrading your valve springs or increasing your valve spring pressures since boost pressure on the valve reduces spring tension. For example, 15lbs boost on a 2.125 OD valve reduces the springs closed seat pressure by approximately 40-45lbs.\u003c\/li\u003e\n\u003cli\u003eAll MARINE Applications - We strongly recommend Inconel exhaust valves \u0026amp; also offer a hard anodized coating to slow the effects of corrosion. Please see note on guide clearance below.\u003c\/li\u003e\n\u003cli\u003eValve Guide Clearance - Your AFR Heads come with proper guide clearance (.0012\"-.0016\") for most applications. Boosted\/Nitrous or marine applications might require additional clearance and it is the customer's responsibility to verify proper clearance in these applications.\u003c\/li\u003e\n\u003cli\u003eValve Springs - Forced induction, nitrous oxide and cams with aggressive ramp rates may require additional spring pressure. We offer optional valve springs for these types of applications. AFR also recommends the use of billet cam cores and short travel Hydraulic Roller lifters which tolerate higher spring loads. Please don't hesitate to contact us directly if you question which spring is correct for your application.\u003c\/li\u003e\n\u003cli\u003eAFR Titanium Valves - Might require lash caps and different length pushrods. Titanium valves are coated, do not grind valves because it removes the protective coating.\u003c\/li\u003e\n\u003cli\u003ePiston to Valve - AFR assumes no responsibility for damage if the end user builds an engine without properly verifying he has enough piston to valve clearance (depth and radial clearance both checked). We recommend a minimum depth of .080\" on the intake valve and .100\" on the exhaust with a radial clearance of .020\" minimum around the perimeter of each valve. Clay is recommended to visually verify both depth as well as radial clearance. Just checking depth is not enough, the position of the valve pocket must also be addressed. It is the customers responsibility to verify proper piston to valve clearance.\u003c\/li\u003e\n\u003cli\u003eCNC Porting - Occasionally a 100% CNC ported head might have a very small area left \"as cast\", this in no way affects performance.\u003c\/li\u003e\n\u003cli\u003eShaft Mount Rockers - Shaft mount rockers might require additional clearance for proper pushrod fitment. Do not clearance the push rod area as the wall is .060\" thick. If you use Jesel Shaft Mounts, AFR only recommends their Pro Series.\u003c\/li\u003e\n\u003cli\u003eComp Cams Pro Magnum Rockers - Typically these rocker arms do not clear a 1.500\" O.D retainer. A lash cap is required to space up the rocker arm.\u003c\/li\u003e\n\u003cli\u003eSpring Installation - To ease installation with 1.550\" O.D or larger springs, 12 pt head bolt or studs are recommended for extra clearance. Beveled or ground washers might be needed (ARP #200-8504 comes with smaller O.D and doesn't need to be ground)\u003c\/li\u003e\n\u003cli\u003eValve Spring Installed Heights - AFR valve spring installed height spec is +\/- .015 which is the smallest shim available for adjustment.\u003c\/li\u003e\n\u003cli\u003eRocker Arms - Use full roller rocker arms, roller tip rockers with stock style bodies are NOT recommended.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Aeroflow Performance Products","offers":[{"title":"Default Title","offer_id":49518917255479,"sku":"AFR1001-FT","price":1298.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/386844_d7bfeeb0-a178-40bf-926e-c8e3a86b774c.jpg?v=1779362733","url":"https:\/\/enginemaster.com.au\/products\/afr-1001-ft-chev-small-block-195cc-enforcer-cylinder-head-w-flat-tappet-spring-option-each","provider":"Engine Master","version":"1.0","type":"link"}
