Hi guys,
Did a quick search but didn't really find what I was after.
Basically I just want to know peoples opinion on metal head gasket installation, specifically tomei. I am helping a mate out with a 25 build, is it best practice to use hylomar on installation or not?
I was under the impression they have a viton/butal coating which eliminates the need for this, I just make sure both surfaces are clean and good RA, then install. What does everyone else generally do here?
Cheers.
