Seal the base gaskets with Curil T. No oring is necessary.
Curil T is non hardening and will seal the cylinders even considering they are constantly moving. Curil T is an Elring product available from many sources including Supertec Performance.

In a perfect world, cut a groove inside the spigot and install an oring there. In lieu complete disassembly and machining, Curil T is the answer.

At Supertec, we warranty engines against leaking for 2 years. This is one of the reasons we can offer this warranty.

Question: Did you say the heads were torqued to 36 lb.
This seems very high. We would only recommend these high numbers for 500 plus horse power turbos but these kinds of number are excessive for most engines.
Are you certain that was not the torque number for the rod bolts?
