cheap way to lower compression

Post Mon Sep 18, 2006 11:12 pm

What kind of compression will I get by putting an m20 325 head onto a 320 block with standard pistons? and will it hold boost?

Will the head gasket not seal?

i think the gasket will seal, but it will create a horrible combustion chamber that will over hand the sides of the cylinders onto the block

there was a thread about it in tech fairly recently..

What about fitting a thicker headgasket or getting a decompression plate made?

yes they would work but why do it toa 320 with small ports higher compression build a good low comp engine

find all thebits and do things properly not just bodge
