Head Studs
I haven't bought my truck yet, im still runnin the '86 for now. However, i know when i get a PSD, i know i will be PMSing. I allready have a list of mods to do to it. Appearently these things are like 275 hp stock right? At what point would it be recommended that I go with installing head studs to keep from blowing the heads off these things?
How are head studs installed anyways? I hear they are a pain in the @ss but i don't kno how.
thanks!

you can do them with the motor and heads in the truck or you can pull the motor and then pull the heads.
if you get stages 2's or bigger and a bigger lung. (over 40 psi) i would put them in. if not you will lift the heads from the stock bolts stretching.

I believe once you get above 40-45 psi boost is when it is required.
Excuse the ignorance, but it seems to me that if you do them with the head on and you remove one head bolt at a time aren't you risking the gasket integrity since it is not torqued at that moment?

Doing one at a time will work. Neal there will be enough squeeze on the gasket with all the other bolts in place that it will not hurt anything. Most guys when doing studs and not the rest of the engine do them one at a time and I don't recall any one having problems.

After doing half a side i decided it would be easier to just pull the engine since my trans was out getting freshened up anyway. I pulled one headbolt at a time and replaced it w/ a stud torqued to factory specs. After all the bolts on 1 head were replace i went back through and final torqued the studs up to 135 ft/lb. If your doing the install in the truck you have to rock the engine back or jack the cab to get to the back stud on each side or i believe some have drilled a hole through the firewall to gain access.

now it's 500+hp and runs the quater in the high 12's, but to get thier it will eat up some big $$$$
doing headstud with the motor in the truck is not a hard job you just need to jack up the cab for the back 2 studs(1 on each side).do one at time is the only way if all you going to do is head studs
