i dint know the rocker arm assembly shared the head bolts i apologize for not doing more research. tools and mechanical know how are not a problem for me. i have a automotive and machine shop to tinker in. you have a excellent point why mess with it if it works so well. i just wanted a project i guess but maybe i will wait tell i need to rework the motor because i don't really want to spend that much money on it now and i am loving the reliability of this thing. its slow as hell but dam it is nice how well it runs. i crossed over from VW/Audi land of break downs and overpriced parts.
anyways im done ranting now i guess i will just have to start working on my 912 targa project. <img src="/forums/images/graemlins/cheers.gif" alt="" />
