Gentlemen,
An update on Brass head gaskets: They are NOT torque once and forget them.
They require retorqueing: after a solid heat cycle you need to brake lose and retorque each head bolt (one at a time) in the correct torqueing pattern.
As my engine is going into a G20 Van it is nearly impossible to do a retorqe.
I have had to use SCE Cylinder Head Gasket M110628; MLS Spartan .028" x 4.067" for Chevy SBC for my engine as they are true Torque once and forget them.
This new information was provided by SCE tech support; saying, failing to retorque I would be risking water or compression leaks.
This was also supported by my talking with Milodon at milodon.com who said they stopped using and selling copper head gaskets a decade ago, and he told me I needed to add RTV sealer to every water passive hole in the block and the heads or have water leaking into the combustion chambers or vice versa.
Damn I nearly made one of those major engine killing mistakes I have had nightmares over.
I was worried about scotch bright scrubbing pads the gaskets to remove all Spray Copper sealant…and OMG learned I nearly ran my engine with doomed to fail Copper Gaskets.
