Until now, there weren't many options available when it came to aftermarket head selection for the Clevelands. Now, that's all changed with the Performer RPM head for 351C.
Designed to work with the 351C, 351M, and 400M, they feature very streetable 190cc intake runners with 2.05" intake and 1.60" exhaust valves that provide more than enough volume for outstanding power to 6500+ rpm. Not only do they offer superior flow over a stock Cleveland or 351/400M head, but they also offer the flexibility to work on the standard 302 or 351 Windsor block to build your own version of a Boss 302, or the infamous "Clevor" engine! The intake and exhaust ports are in the stock location to further add to the streetability of these heads, and can be made to breathe even better with minor port work. Made In The USA!
