Re: Head and Intake Gasket Suggestions
The blue fel pro gaskets that you get over the counter are ok but very generic and probably won't fit your application.
Do it right and measure the ports and you may even need a thicker gasket.
I used the otc fel pro gaskets last 3 times and with a decked block, 190cc intake runner heads milled the gasket hangs into the intake runner and is leaking in 3 different ports bad. Now I will go back, measure and buy the good quality gaskets that fit my application.
Mr. gasket are good.
As for the head gasket since you block hasn't been decked use a .025" composite head gasket from competition products.
I'd tell you to use a .015" shim steel but it probably would not seal well because your block was not recently machined, or your heads.
