Can i use 2 head gaskets or do the make thicker ones to lower my compression? Then use a sohc block with dohc head. Is it worth it? How much will it lower my compression?

 

you can but not advisable at all... you can get one that is thicker just for that purpose...

 

If you use the SOHC bottom end with the DOHC head you'll have 9.4-1 compression which is almost ideal for turbo charging. The DOHC bottom end has flat toppistons and the sohc has a small dish which would work better to get your compression down. I say the DOHC head on the SOHC bottom end alone is enough of a drop in compression.

 

So should i not use a thicker head gasket? I only plan on running around 10 pounds of poost. But i was to be safe not sorry. Where would i find a quality thick headgasket

 

DOHC pistons are domed to increase compression.

Just use a quality HG!
