AFR Performance Cylinder Heads from RPM Machine we meet or beat anyone on the web

 

AFR Air Flow Research Cylinder Heads LS1/LS2/LS6 From RPM Machine

For the ultimate street LS1/LS2/LS6 aluminum head AFR’s all new 210cc emission legal heads E/O # D250-4 are your only choice. Specifically designed for 1997 to present Gen-3 Chevy Corvettes, Camaros, and trucks. AFR’s LS1 head offers unmatched flow performance (298 CFM at .600lift) and features 2.020 intake and 1.600 exhaust valves with AFR’s iron ductile interlocking valve seats. With only 205cc port volume (same as stock LS1 head) this is an incredibly 70 CFM increase over stock casting creating unbelievable port velocity. The 210cc is ideal for normally aspirated 346C.I. to 396C.I. It is available with 66cc combustion chambers.

In keeping up with the GM’s trend of larger bore sizes and increased displacement, AFR is proud to release our 215cc LS1/LS2/LS6 version of our popular Gen III product line which is aimed specifically to maximize 4” bore combinations (364 – 408 CID). However this head is very versatile and could also be considered for aggressive 346 applications and should also be a prime consideration in larger stroker motors as well (415-430 CID) if the focus of the build is more aimed at enhancing street performance than all out strip performance (where our 225 or 240 cc offerings potentially make more sense). This is a very effective design offering serious velocity
while still being able to provide a significant volume of airflow enough to generate well over 600 HP at the crank.

For the maximum street/strip LS1/LS2/LS6 aluminum cylinder heads AFR’s all new 230cc emission legal head E/O #D250-4 are hands down the best choice. Specifically designed for 1997 to present Gen-3 Chevy Corvettes, Camaros, and trucks. AFR’s LS1 head offers unmatched flow performance and features 2.080 intake and 1.600 exhaust valves with AFR’s iron ductile interlocking valve seats. The 230cc is ideal for normally aspirated 396C.I. to 427C.I. For a wild 346 ci the 230 is a
good choice, however some low RPM loss of torque might occur. It is available with 62cc, 65cc, and 72cc combustion chambers. AFR’s LS1 is a direct bolt on, no special parts required. Structural features like Air Flow Research’s trademark 3/4” thick head deck, a must for blown and nitrous applications, reinforced rocker stud bosses and thick wall runners provide unparalleled durability.

A tremendous amount of time and energy was invested to bring you our 245cc LS1/LS2/LS6 Gen III head that represents the pinnacle in cathedral design bolt on performance. With over 350 CFM’s available it has intake flow numbers approaching GM’s famed (and much larger) LS7 head with much stronger exhaust flow in comparison. This head is our take no prisoners LSX cathedral shaped offering and its focus is large displacement combinations (415 – 454 CID) with a minimum bore size of 4.060. It requires a head gasket bore of 4.160 or larger and comes standard equipped with lightweight 2.160 intake valves / 1.600 exhaust. Another unique feature of this head is that it is “solid roller friendly” having been designed and machined to accept larger .375 push rods without additional clearances (in most applications) and comes direct from the factory with 1.570 spring pockets (Note: Under no condition can these pockets be machined deeper).
