Re: Head Gasket/Head bolts
More likely you have stock clearances, ie. piston in hole , which usually is .025 or so. If thats the case, I would use the thin .015-.019 shim gasket. Spray with silver paint or Permatex Hi tack just to be safe .
If you can't afford head studs, you have the option to use what you have or go for a decent set like Mr gasket head bolts and washers or the Pioneer brand. Washers will help you get a good torque reading, keeps from eating head bolt hole faces.
I would also recommend you use some type of sealer on bolt threads. Permatex Indian Head shellac is fine. This will keep the bolts sealed as they pass thru the water jackets.
The gm brand gasket is fine. Felpro has one also , I believe the number is 1094. Its rubber coated for seal purposes. GM gasket is not .
You will also be looking to cut your quench area, (piston deck to head deck) , this help detonation.
Make sure your valve seals are in good condition . Springs are off so replace them.
On the cam side, you need to add some type of break in lube. Comp has an additive, might use this or GM EOS , if you can find it. Be sure to coat each lifter and lobe with the moly breakin paste. Use some Rotella 15-40 oil for start up break in, probably would not hurt to leave it in or continue using it.
