Ok I've got $2000 for this pi swap I know its not enough but I'm working overtime for this one. I'm doing install no prob there. It's the heads man so many specs, diff spring heights wtf. I'm wanting fully ported and polished pi heads with stage 2 cams and adjustable cam gears. The springs and valves are giving me trouble, what to get? Diff. valve sizes, valve angles Idk what is up and what is down anymore so many different shops doing these heads now, all with there own specs. patriot, d.s.s. d&d, just to name a few. kinda want to set things up so when I get my twin turbo I only have to forge bottom end and change pistons to lower comp. (next winter) Any help would be great.
