stock head gasket question

[240sxproblems]

I had my block bored out to 90mm from the stock 89mm bore. I was wondering could I use a stock head gasket with that bore or would it leak.

As long as it doesn't shroud the bore then you would be good, but I doubt that it wouldn't. The Felpro I used was just about 1mm larger than the bore. If you did use it, it will blow again. But like I have said, the Felpro should be large enough.

I used a fel-pro but I am going to pull the head back off and see if that is what it is. I am not sured why it keeps blowing .

Are you using new bolts and torqueing the head down in the right order, and to the right spec? Are you sure the head is flat, how about the deck?

[240sxproblems]

yea I have new bolts and I am using the right torque and sequence.

Did you check the head and block to be sure that they are true?

[240sxproblems]

the shop that did the head and block work did. Iam going to take it back to them.

Are you installing the head gaskets dry?
