Clone high comp head

Hi-Compression 14cc head with 5.5mm valve guides and valve seats installed to accept 25/24mm valves. Great for a stock appearing class because it looks like a standard clone head. The combustion chamber is 8cc smaller than the standard clone head which gives you a nice boost to compression. There is room for additional milling of the gasket surface to get even more compression and the ports have a little extra meat for porting mild to wild. The dowel pin holes are the only difference between the two options.

The Non-hemi Gen3 RTC 27/25mm valves will not work in this head because they have a 5mm guide and Predator Hemi engines (Gen 2). 27mm intake valve will not work in this head. This head uses 5.5mm stems  and 25/24mm valves. We recommend upgrading to stainless valves.
