SM Head Modifications on a budget

I'm fabricating a 5" long 2% tapered intake entry plate that will act like a perfectly straight intake manifold runner. I want to test the pushrod pinch changes with a different entry plate. I hate the phrase but I'll use it here. What if the flow bench is lying to us? With a short entry plate we basically have a venturi right at the port entry. That could do weird things and certainly different things than in a running engine.

I like that idea. Bolting on an intake or at least a runner like you are saying is eye opening.

As for the cutter blades, I asked because I’ve seen 4 or 5 angles on the B sized cutter but once you get more than 3 angles on those you are out of room to make the cuts much more than .100 wide if that.

When I was buying cutters or when I was developing a cutter I always put them on the A cutter so I’d have more room.
