The heads for this motor project were done years ago and over time some very, very light pitting has occurred on the head intake mounting surface. I typically don't use any sealant on intake gaskets, but in this case I was thinking about a very light ("skim") coat of high temp RTV silicone (orange). I thought about the spray copper sealant, but the directions say to spray both surfaces and since the heads are already on the block, that would be messy and/or require alot of masking. Any thoughts?

Thanks,

Rono
