When I do my roller rockers this winter, I was going to get 7/16 NSA with 7/16s studs ...

My question is:

Dont the old ones just thread out and the new one threads in? No need to re-tap the heads correct?

I was under the impression that I wouldnt have too, the head side of the studs are the same thread/pitch.

However, some guy yesterday was telling me I would have to pull the heads and blah blah blah to get them to tap them to the correct threads and that its not worth the work. I was almost positive he was wrong, but now im second guessing myself ...

Also, Is this everything I'll need for the job ?

Comp Pro Mag's 1.6 RR
GM Guide Plates
LT4 Springs, Locks/Retainers
Valve Seals ( While im in there )
Valve Spring Compressor

Also, since my car is a 95', it has hardened push rods, so wouldnt it be pointless to upgrade them now? I was going to wait until I have the money all saved to build my stroker motor.

 

If youre talking about the heads that came on your 95Z you are correct. The guy you spoke to yesterday would be correct in the case of LT1 iron heads & most/many other heads which have pressed in studs which you would indeed have to tap for new studs.

 

Correct, for an LT1 F-body.

 

I would still do the pushrods, only because they are like $35 from thunder racing, might as well do them right then. Also you will prolly need new valve cover gaskets, and you could get new spring seats as well, but its not as important. BTW I have basically the same setup, but different springs.
