Speedmaster Small block porting tips and results Part 1

I'm a bit apprehensive about running a 50° seat in such a flat chamber, one would have to sink the seat quite a bit to get this profile. But I'd love to try it.


LOL. Me too. That flat chamber always makes me nervous BUT, even with a decent 45 it's damn hard to get a good, full top cut in there without sinking the valve.

Used to be when someone said "sink the valve" anyone standing there would go apoplectic, lose all the color in their face and then they'd call a priest in to do an exorcism on you for speaking that voodoo.

Skimping on the top cut is a no no.

But yeah, the flat chamber makes me nervous too. As PRH so well says...iiwii and that's about all you can say.
