Help choosing head gasket..
Hey guys, i need some help choosing my headgasket for my gsr turbo build. I rely on you guys, since it will be my first turbo motor, and yea, you can say i went all out on this. I wanted it to be a very reliable street car and maybe will see the track once a year for 5 or passes each time. Mostly it will be driven on the street tho, so looking for a headgasket that will be of good quality and last me awhile.
I know about the OEM reliabilty, and golden eagle's modified OEM gaskets, but im still a little confused, so i will post my setup and hopefully you turbo gurus can help me out a little...
block
GSR block
Benson 83mm sleeves
CP pistons 9.0:1
Manley I beams
ACL bearings
Block was slightly decked for smoothness and straightness.
Head:
GSR head
Stock GSR cams
ITR valve springs & Retainers
Ferrea 6000 Valves
OEM valve seals
Ferrea Bronze valve guides
Skunk2 Manifold w Hondata gasket
Head is built by Headgames and was slightly milled for smoothness and straightness
Now, according to the Zealworks compression calculator, im looking at about 9.1:1 compression i believe. Can you guys confirm this?
With a stock .030 headgasket, I would keep the compression at that, but i would like to be at 9.5:1 or 9.6:1 to make it a little more streetable and responsive at lower rpms.
Is this a good idea? To want to up the compression? If so what headgasket would i need...obviously a custom 83mm bore would be needed, but im not sure about the thickness or where to find it.
Unless you guys can convince me otherwise, that this 9.1 or 9.2:1 compression would be worth it for the street...
Turbo will be a Garrett 57 trim, .63AR...
I want a quick spool and good power...
Any help would be greatly appreciated...

Re: Help choosing head gasket..
No need for o rings on benson sleeved blocks...
I was looking at just removing the middle layer of the oem head gasket, bringing it from .030 to .020, therefore increasing compression by about .3 or so...putting me right around 9.5:1

Re: Help choosing head gasket..
I guess the only company i can go with is Golden Eagle, as they are the only ones that seem to make bigger bore OEM hgs.
Buddy club, spoon, mugen, etc all make standard bores, which would do me no good and the price is crazy...

Yea ive been looking into Cometic as well, and i know they are of good quality...But i think the thinnest size they make is .027 which is almost like stock right?
If they would have made a .020 i would have jumped on it.
