fel pro head gaskets suck!
only use multi layer steel gaskets.... OEM is the best, the stuff that engnbldr.com sells is also very good
FELPRO HEAD GASKETS ARE CRAP AND SUCK!
Pretty much jimbo said it all.
I ran one fel pro head gasket and it was fine but I must have been one of the lucky people because even when I put it in, i knew that there is a high chance it will be no good pretty quick.
