I fired up my new rebuilt 117 inch RevPerf Super Billet Head motor today. I still have a few things to take care of as I need a larger diameter head pipe exhaust because I have an exhaust leak. The heads are top notch...my compliments to Brian and Dusty for the incredible work on the heads, intake, and pistons. The motor fired right up, has oil pressure and is getting oil to the rockers......This is going to be a really cool build once I get the Zippers "D2" sorted out and the exhaust issue addressed. Cranking Compression is 225 front/222 rear with the Wood TW-68G cams.
