Product Description

245 LSX Mongoose Strip Cylinder Heads

Our Max Effort Cathedral Port Offering

 

A tremendous amount of time and energy was invested to bring you our 245cc LS Gen III head what represents the pinnacle in cathedral design bolt on performance. With over 355 CFM 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 AFR's take no prisoners LS cathedral shaped offering and its focus is large displacement combinations (415 - 454 CID) with a minimum bore size of 4.00

The dual quench pad combustion chamber design requires a head gasket bore diameter of 4.200" or larger. These heads comes standard equipped with lightweight 2.160" intake and 1.600" exhaust valves. Another unique feature of this head is that it is “solid roller friendly” having been designed and machined to accept larger .375" diameter pushrods without additional clearancing (in most applications) and comes direct from the factory with 1.510" diameter spring pockets (Note: Under no condition can these pockets be machined deeper).

With an aggressive set-up this head is capable of producing power in the 700 HP range while still providing gobs of low and midrange torque. It is still a factory direct bolt on with standard length valves, stock valvetrain geometry and everything in their respective OEM locations. This race-bred head comes with AFR's trademark 3/4” head deck and the same rugged castings found in the rest of the AFR LS line up. Make sure you’re packing lots of displacement to fully realize the benefits this head can offer you and hang on when its time to go WOT

NOTE: LSX bead locks and aftermarket bead locks are not interchangeable. GM made their bead lock radius and depth different. AFR locks are the same as GM LSX.
