To help quench the thirst of that large displacement monster AFR is proud to offer the largest direct bolt on 23° Chevy head yet. At 235 cc's, anything under 400 inches can look the other way. It has the same geometry as the 227 head and will accept all the same rocker arms, stud girdles, etc. AFR offset stud girdles are the only special parts required. Some applications require shaft mount rockers or .050 offset intake rocker arm for durability and reliability of valve train components. Standard rocker arms can be used but the intake rocker arm will be at a slight angle and the roller tip will not be perfectly centered on the valve. It will feature a larger 2.125 diameter intake valve. Exhaust valve diameter stays the same with a little more flow from its larger runner volume. The big news is our all new intake port design which pushes this standard location intake port over 335 CFM's! That's 18° territory and this head should be able to generate power figures that rival those heads (725+ HP). \u003c\/p\u003e \u003cstrong\u003eBasic Package Components:\u003c\/strong\u003e\u003cul\u003e \u003cli\u003e \u003c\/li\u003e \u003cli\u003e100% CNC Ported Combustion Chambers\u003c\/li\u003e \u003cli\u003e 100% CNC Ported Exhaust Ports \u003c\/li\u003e \u003cli\u003e100% CNC Ported Intake Ports\u003c\/li\u003e \u003cli\u003e3-angle Radiused Valve Job\u003c\/li\u003e \u003cli\u003e Bead Lock Intake Valve, 2.125\" x .100\" long \u003c\/li\u003e \u003cli\u003eBead Lock Exhaust Valve, 1.600\" x .100\" long\u003c\/li\u003e \u003cli\u003e 1.550\" OD Roller Dual Valve Spring, 225 lbs on seat, .710\" maximum lift \u003c\/li\u003e \u003cli\u003e10° Titanium Retainers\u003c\/li\u003e \u003cli\u003e 10° Bead Lock Valve Keepers\u003c\/li\u003e \u003cli\u003e7\/16\" Rocker Studs\u003c\/li\u003e \u003cli\u003eGuide Plates\u003c\/li\u003e \u003cli\u003eViton Valve Seals\u003c\/li\u003e \u003cli\u003eHardened Spring Seat\u003c\/li\u003e \u003cli\u003eIntake Valve Seats\u003c\/li\u003e \u003cli\u003eExhaust Valve Seats\u003c\/li\u003e \u003cli\u003eBronze Valve Guides\u003c\/li\u003e \u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003e","brand":"AFR - Air Flow Research","offers":[{"title":"Default Title","offer_id":44538075578679,"sku":"AFR1132-TI","price":6969.8,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/34818.jpg?v=1780689130"},{"product_id":"air-flow-research-afr3350-chev-bb-cnc-cylinder-heads-335cc-121cc-bare","title":"Air Flow Research AFR3350 Chev BB Cnc Cylinder Heads 335cc\/121cc Bare","description":"Air Flow Research AFR3350 Chev BB Cnc Cylinder Heads 335cc\/121cc Bare","brand":"AFR - Air Flow Research","offers":[{"title":"Default Title","offer_id":44538172080439,"sku":"AFR3350","price":7708.3,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/629714.jpg?v=1780803480"},{"product_id":"air-flow-research-afr7422-chev-bb-18-tulip-exhaust-valve-11-32-1-800","title":"Air Flow Research AFR7422 Chev BB 18¡ Tulip Exhaust Valve 11\/32\" 1.800","description":"Air Flow Research AFR7422 Chev BB 18¡ Tulip Exhaust Valve 11\/32\" 1.800","brand":"AFR - Air Flow Research","offers":[{"title":"Default Title","offer_id":44538173292855,"sku":"AFR7422","price":58.1,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/620719.jpg?v=1780649785"},{"product_id":"air-flow-research-afr2020-chev-bb-magnun-385cc-full-cnc-comp","title":"Air Flow Research AFR2020 Chev BB Magnun 385cc Full Cnc Comp","description":"\u003cp\u003eAs the aftermarket continues to push larger displacement combinations, even 555 CID BBC's are becoming commonplace with 600+ CID engines more plentiful than ever before. AFR is proud to announce our answer to that with our all new 385 cc Magnum, the largest and highest flowing BBC product in our line-up with flow numbers that are creeping up on many of our competitor's 18 degree Pro-stock style heads. If you've got the displacement we have the head to feed it with an intake port that flirts with 440 CFM at a usable lift-point, and enough complimenting exhaust flow to still maintain over 75% of that number @ .800 lift (335 CFM's at .800 lift!). While this huge a runner is more clearly aimed at 572 - 632 CID applications, in a light car it could still be considered in 555-565 CID aggressive builds that are built to reliably turn 7800 - 8500 RPM's (Ti valves recommended over 8000 RPM's). This head will be best utilized with camshafts in the .780 - .850 range to take full advantage of its impressive higher lift airflow, but the best thing about this head is its ability to also provide the end user with industry leading low and mid-lift flow as well (400+ CFM at .600 lift!). This head of course comes with AFR's trademark .750 thick head deck, reinforced rocker stud bosses, and is equipped with 2.350 intake \/ 1.880 tulip exhaust valves.

AFR's 325cc Magnum big block Chevy line of medium-volume intake runners will provide you with exactly that. The phrase \"having your cake and eating it too\" would certainly be appropriate with their moderately sized intake runners producing tremendous flow figures across the entire lift range. These high-flow\/high-velocity ports provide extreme versatility and fill the needs of many applications. From a max-effort high-compression 454 to a 605 c.i.d. low-rpm marine application, these aluminum cylinder heads would be a great choice. AFR Magnum heads would also be ideal in larger cubic inch Pro Street applications with their broad torque range, as well as their significant rpm and horsepower capabilities. These cylinder heads will work best with a primary operating range of 3,000-7,000 rpm (this range is an average and will vary with engine displacement as well as component selection). These 325cc heads come standard with AFR's trademark 3\/4 in. thick head deck, reinforced rocker stud bosses, and premium one-piece stainless steel 2.300 in. intake and 1.880 in. exhaust valves.
