Okay, they are really soft btw...a small push with your nail will show immediately... And I ordered the bolts with Todd...thanks again for the tip.
Anybody have a picture here of the Remflex gaskets installed on a 400 or 430 with stock manifolds? Would like to see how the gasket fits without it's being trimmed.
Surface grinding an iron manifold takes just a minute or 2 and lasts forever if the bolts stay snug. Never remove one that is still warm.
I used Rem. they are chunky and very apparent. I don't really care but you can't miss them. I'll try to snag a pic. So far so good in terms of use.
