cylinder head - no gasket
I know it's here somewhere, but I cant find it - I know SOMEONE will go on about using the search. I have. I cant find the thread that I was sure I read about a month ago.
Anyhow, I'll be putting my av7 back together soon, and read that its best if you leave the head gasket off (to raise compression). If I remember this correctly, something needs to be used to make a proper seal between the two surfaces.
What is the product I need?
