hi i just want to ask Are all D series headgasket the same ? some are cheaper then other im trying to put a mini me together d16z6 head with a Y7 block i got the block for $50 is this a good combination for boost ? Because the compression is going to be like 9.6 not 9.2 like my old z6 thank

 

im running a y7 block and y8 head. my compression with my srp 9"1s is like 9.7 to 1. im boosting 10 lbs right now on a stock y8 head gasket and its fast. im uppin it to 15 lbs this weekend. ill let you know how it hold up

 

get the y8 head gasket. and, you'll save some money.
i got mine at www.hondaautomotiveparts.com

 

i heard the y8 gasket is thiner then the new design of the z6 gasket right ?

 

what is the stock compression ratio of the d16y8 is it like 9.6 :1 ? anyone boost 10 psi on it ?

 

d15z6 head gasket are quite thick they have tendency to be fragile.

 

A6 composite .043
Z6 MLS/metal .043
Y8 MLS/metal and I've heard it's thinner.

My A6 composite has seen 16psi... Head studs help.

 

I use z6 head gaskets on all my single cams.
