Head gasket thickness miss conception

[Johnoolo]

Alright my fellow forums junkies im back finally back the MSP has been dead for a while, but i am about to begin its revival. I have read a lot of conflicting things on head gasket thickness some people said stock some people say .30 or .51. this is staying a stock block so the bore is 84mm if i remember correctly( please correct me if i am wrong) i want to run about 11 pounds of boost on a tuned ecu with full bolt ons. Help shine some light for me please.

Stock is 83mm. 0.02" overbore is 83.5mm and 0.04" overbore is 84mm.

I'm looking at a MLS headgasket on speed circuit but none of the options are for an 83mm bore? It's a stock block but I'm replacing the head on it with an fs head

To be safe you could just get a stock thickness Fel Pro MLS HG, unless you are wanting to lower the compression

I went with an mls head gasket at .30 not a huge difference hope it works out well
