Default Compression for ITR block with GSR head?

My friend blew his GSR motor and picked up an ITR shortblock from Acura. Can anyone tell me what his compression would be with a Mugen head gasket? Thanks in advance

11.1:1

itr block plus gsr head = 10.8:1
mugen head gasket =.3-that may be on the high side

Wrong, wrong, wrong. Fast 94GSR is the closest.

Do the math. GSR has a 41.6cc combustion chamber.

10.88:1 for a NOT milled head on a NOT milled block with a OE gasket.

With a Mugen gasket, he'll be about 11.27:1... but I am not 100% sure because I don't know exactly how thick a Mugen gasket is.

I have a compression chart in .bmp format if anyone is interested.
All math was done properly, and I rechecked everything.
It lets you pick what block, what piston, what head, etc.

If someone wants to host it let me know and I can email it.

LOL.. wrong wrong wrong? i said 11.3 and you said 11.27. wtf?!?

stock R block and gsr head = 10.88 as you said... add the mugen head gasket just like the original question poses and you get 11.27 or for all intesive purposes 11.3 just as I said. Man I gotta come down to FLA, the good **** must be in season.

around 10.8 ,that would be with a stock head gasket and since the gsr head combustion chamber are smaller it creates a bit more CR then the type R head and b16 which are almost the same !
