If the head isn't leaking at the gasket surface and compression test shows favorable results, then I'd be inclined to believe it was acceptable machine work.

 

this is very true looks like its time for a compresion test

 

ok the kid who the car before ran 15 psi blew the head studs out the first time then he put arp head studs in it blew those out once again runnin 15 psi on a shaved head he put the stock ones back in , he sold the car to another kid this kid ran like 12 psi blew the studs brought it to his mechanic he put studs in it . Then he sold it to the kid whoe has it know,its got a exhaust leak more then anything. But the head is ticking so rather then go through all of the trouble of fixing the head hes just going to get another that isnt shaved so he can run 15 psi no proublem. Sorry philly i had to say it, i proubly know more about his dsm then i do mine i dont know whoes ive been under more, lol

 

What do you mean you blew a head stud out.

 

runnin to much boost with it just packin air into the motor not enouhg air space its going to pull somethin out like the studs .
its not my car its just the kid down my street ive known for 17 years.

 

Your kidding right?
Are you saying the studs got pulled up out of the block???

 

thats right you never seen it

 

imwith tom on this one... ive never seen the head studs pull out because of 15 measly psi on a 16G... ARP's are good for AT LEAST 220kpsi on the studs... there needs to be ALOT more than 15psi and knocking to stretch the studs or strip the threads on the deck.

if you want a cylinder head that is complete and never been cut, let me know. i have one in my garage. i would recommend using the 3rd gen HLA's regardless of any route you take.

 

No mater how you look at it. If the studs are coming out of the block then the problem is not the head. But I have never seen it. So dont listen to me.

 

If you still are looking for a complete head, I have one $150, came from a great running 1990 turbo motor.
