HVH Super sucker?

Before I did that I would get a Magna Fuel anti reversion plate.

They aren't horribly expensive and they do what they do better than an HVH type spacer.

You might be surprised what an open hole 2 inch spacer would do.
Oh I know what a 2 inch spacer can do. However as I said, I have a half inch hood clearance to spare.

Maybe I'll get her nice and warm and go over the valves again.
