Hey,
Picking up a new Apexi headgasket for my SR engine. From what I have read, the thickness to buy is 1.1mm and 87mm diameter. Can anyone confirm? I have done alot of reading on this but am still confused as some of the info doesn’t agree with what I read.
I plan on running 300-350hp.
For proper head gasket fitment you should use a 1mm to 2mm larger gasket then the bore. for example the stock bore is 86mm so a 87mm gasket would be used. when choosing a apexi head gasket you will need to pick a 86mm gasket for a 86mm bore because apexi gaskets are actually 1mm larger then the package says it is, the gasket package will say 86 but the tru size of the gasket is 87mm.
