Power levels dont really have anything to do with the kdp, if its not done do it before its to late and it causes serious problems in the long run. I wouldnt bother with head studs if your only looking for 400hp, a 62 or 64 will get you past 400, with under 50 psi of boost. I would search the forums for the technique of torquing the stock ones down tighter, or pm me and ill let you know what I do. This has held for alot of people with no problems. From seeing your sig it looks like you have a built tranny so you are good there.

@ KMK< Im in the same boat as Dude is. Can you drop me a line explaining the torquing of the head bolts?

I plan on doing gauges, tunnel ram, Intake elbow, 4k GSKs, valve springs, AFC, and cold air intake. I should do some timing but not sure where to stick it at. I have also thought about larger injectors but trying to figure out how big to go.Do I need DVs too? I plan on eventually getting a twin turbo set up and of course that will require new head bolts and a clutch.

Thanks in advance
