340 Piston Selection

How would cutting a RPM 340 head kill any flow? Have you actulay seen one of those heads?
Im not saying that im perfectly confident that those heads will take it without problems but that option should atleast be taken a good look at before taking any more steps.

My opinion is that positive deck engines are stupid,unless we are talking about an engine that requires a domepiston then they are just alitle less stupid and its quite obvious that theRPM340 heads are an aftertought.

If his heads have a .060 recess cut in them, the piston needs to be out of the deck.

As for killing flow, you'd have to spend some time on a flow bench. It damn sure does affect flow. Think about how important a top cut is. Then you move the deck closer to the top cut? Bad idea. You can mill a head within reason. To run a zero deck and then deck the piss out of the heads to get the CR you want is *** backwards.
