Been playing with these for the last week or so, thought I would share some pics. Cool valve cover logo.. Chamber measure in at 61CC, the 555 these will end up on, with a flat top piston and .050 head gaskets works out to a nice 14.5-1. Enough compression for the big cams, not so much that exotic race fuel is required. The 7" Titanium valves, compared to a stock Stage 1 valve. Intake port pours to 470CC. Conventional Stage 2 Exhaust port, will require custom headers or extensions as the headers sit higher on the heads. Pressed in hardened washers are a nice touch. On both the valve covers and heads. O ring in place for valve cover test fit.. Close up of the O-ring Just like everything I have seen with the is project thus far, the covers are sweet.. Billet of course, fit like a glove, bolts just drop in.. plenty of precision here... and check it out, 4 bolts on the bottom, and 3 on the top! that makes some sense.. All one can say is .... very cool.. Initial mockups on a raised cam block are complete, with good fit and rocker geometry observed. I have a head and the valves out for flow testing now. We will be testing both 2.450 and 2.400 Intake sizes on a 4.500 bore. Also several valve angles for a few different options for motor combos. An intake that will fit under the STG 2 hood scoop is in the works, as well as a full out dual dominator tunnel ram for testing. All kinds of fun..
