Hey everyone,
I got my new headgaskets today and as some of you remember I had to get thinner gaskets to meet qunech safe area. I got the 1094 Fel-Pro embossed steel shim .015 and I was reading the installation tips for it.
It suggest a surface finish of "55RA (60RMS) or smoother"
if surface is rougher to apply a sealer.
From what I gather RA is roughness average.
My question is how smooth is this in say terms of something like sandpaper or orginal block smoothness. Also what kind of sealer should be used.
Thanks again everyone,
Chris
