well guys i have my heads back from the machine shop. got ques on the head gaskets though. i ordered a set of SCE metal head gaskets that have a compressed thickness of .015 but the bore of the gaskets are much larger than the stock 305 block bore. summit racing says these will work on my 305. the machine shop guys who built my heads says they wont. who should i believe? when you set the gaskets on the block there is about an 1/8" different between the block bore and the gasket bore. there is much less on a set of stock 305 gaskets. what should i do. 305 guys what head gaskets do you run? i wanted a thinner gasket to run

 

TTT

 

I bought Sealed powers head gasket.

 

iam running a set of fel pro gaskets that measure that same 0.015 compressed and seam to be doing fine, they too were a steel shim gasket as they called them, part # fpp-1094

 

I also ran the Felpro 1094 gasket on my 305, it is listed for the 350 but I had no issues with it on the 305.

 

iam running vortec heads so thats why iam using that gasket, i know of a few others using it also on there 305`s
