944S Compression/Resurfaced head
What is the normal and/ or new compression lbs for a 1987 944S 16valve, and what would happen if you use a regular H/G with a resurfaced head?

Compression Ratio is 10.9:1, and if you are using the Victor Reinz head gasket, all they pack in there sets anymore are the "turbo" gasket...no issues with that gasket.
A quick check of the Porsche PET lists the "turbo" gasket P/N 951.104.374.50 for ALL resurfaced heads (including the M44.40 16 valve head)

compression test numbers? or actual compression ratio?
compression test numbers depend on alot of things, the two biggest are altitude and the weather. as long as all 4 are within 10psi, that's "good" |

Compression test numbers. My spare 16v head looks like someone cleaned it up some. I can see the machining on the mating surface to the block. Looks flat with a long square. I was looking for the measuring mark and numbers for the head. I saw it some time ago but can not find.
