Even if everyone on this board "thinks" it might be ok, you still need to check clearance just for piece of mind.

I realize that. I’m asking people who build these cars and have maybe more or less cam on a similar set up if it should clear, before I spend $500 on a cam, that when installed to check clearance cannot be returned.

You should ask TSP this question. With a 60cc chamber and 4 degrees advance in that particular cam it should clear, but by how much I have no idea

Marengo yours ported by TSP? They sink the balances as part of the port job.

wierd I’ll measure when I get them. .048 is compressed thickness, not the thickness out of the box. Dunno why Felpro would sell .051 and .048 listings if they are the same.
