Headgasket for 35-40psi??

[camfast]

I just got my cylinder head redone from the machine shop and I also have ARP head studs. Which headgasket would work best if i want to eventually run 30-40 psi?? I was thinking a Mitsu mls headgasket?? Any suggestion is appreciated. thanks

so keith if i wanted to run let say 25-35 psi for the drag strip and the street would you say
the mitsu 4layer with l19's is over kill??

i feel copper spray wouldn't be a good idea to spray on the hg because when the head heats up it needs to expand a lil and the copper spray wouldn't allow that to happen.. which could cause premature failure?? or at least thats what i was taught in school??

Wow that just sounds retarded..not you but what the school told you.. uhh copper spray isn't permanent "don't ya know Bobby". We sprayed every single 420A head gasket at the dealer and since every single 420A leaks that was a lot of gaskets. I would not spray a composite though, just metal, metal on metal is a horrible sealing surface, that is why we use gaskets

My bad it is the A1s where the body and nut is 1/2" the threads are still 12mm.

Actually, A1's are also 12mm studs and nuts. I think you are thinking of past days when people retrofitted l19 studs from another vehicle to the 4g63. Now days, L19 and A1's come in the standard 12mm variety.

hmmm really didn't know that was the case.. for some reason i was under the impression that copper spray dose not expand with the mating surface its inhered to; which allows leaks.. metal to metal i understand but composite i would say other wise.. correct me if im wrong

What turbo will you be running? Mine did fine with standard arp studs and a cometic hg at 35psi with the 60-1. Also worked well street driven at 28psi on 93 pump gas. I only went to the L19's because of what the future holds, which you already know about.

thinking about the FP HTA that Jeremy was running in his white 1g or a lil smaller
and when you going to update that thread man?? its been a while??

hta88? You can use standard arp's or go L19/a1 route for the extra insurance.

Off topic, I dont go to the TT board very often. Currently, the car is sitting with the old shortblock, new cams, springs, SMIM, 4.6 mustang 75mm tb, L19's, 1150's, same turbo, link, etc. The fuel pump currently isnt keeping up with demands over 25-26psi. Im just saving $ now for a denso supra tt intank pump and an 044 inline. Justin drove it a few weeks ago but it was doing what it is doing now, just worse now. He was amazed at how well it pulled at lower boost levels. Ask him, he will tell you. Oh, He did get a chance to see that my 30psi boost gauge just isnt enough anymore,

I added a couple new pics to myspace last weekend.
