**Milling .030 off '920 - 273 heads**

Thanks for all the responses, guys!

Rocky...I'm using the .025 Mopar Performance gaskets now with the '302' heads. The 302's have a~62.5cc chamber and the old '920's have a~57cc chamber, so, I was thinking of milling .030 off the original 920's surface, and heads' intake face (so as not to have to mill an original 4 barrel Commando/Charger intake) to up the comp a bit to take advantage of the custom cam I had ground.

Mike...thanks...I'll check out your build thread...I had forgotten about that.

74Dusted....I hear you on the 273-specific gaskets being NLA. I'm using the thin MP ones as I thought that would be the best substitute.

Max...I was thinking about maybe running a hydraulic cam, but was concerned whether the stock hyd. lifters (using stamped-steel, non-adjust rockers) would adjust to the .030 less distance.Shimming the shafts would be the answer there. (I have all the hyd rocker gear for a swap)

Thanks again, guys...all good "grist for the mill", pardon the pun!
