Intake gasket blow outs

In the absence of other responses... I'll share my thoughts...

If you're installing these gaskets... following the properly torqueing pattern and meeting the requirement...it may suggest a deck or head not being square or true. One failure is acceptable, 2 failures suggests that the gaskets may not be the issue.

If those aluminum heads ever saw a lot of heat... they could warp easily...it only takes 1,000s of an inch to give you hemorrhoids...


Since you have to replace them once again... I would give some thought to having the heads checked and/or shaved true. If this doesn't fix it ...well damn... start asking questions about the iron block deck.

Would prefer to hear that you made a mistake on gasket installation.. or that your torque wrench is screwed... lots of guys set a torque wrench for a particular task... and then they don't back off the wrench (back to zero) for long-term storage. I've read this can compromise the readings on a torque wrench.

I would use 1250 gaskets on afr185's, I use 1262r gaskets and have never had a problem, it is also possible that your intake is warpped, have a machinest check it for runnout.

Try the 1262-S gaskets. Same gaskets with a steel core. That's all I run now.
