d3 milling question

whats the most you can safely cut off a set of d3's

I have a set of D2ve's I milled .100 I would think you could mill D3's that much if you didn't get into the intake seat.

What did the chamber CC to and did it kind of convert it to a quench type head. I know this is an old post, but it caught my eye. What did you use it on and what where the results?

72 cc and it was on a 514 13:1 3200 LB 6.20's 111 mph it had a small pad about 2 inches, not enough to do any good in my opinion for quench. The entire valve margin hung below the deck.

Thanks for the reply.
