Default 799 milled?

Ok im am lost when it comes to cc's and all the other stuff?

I have a guy wanting to trade me for my trex cam...they are a set of 799 heads but they are milled 30 thousandths ....

what cc's would that put me at??
I plan on building a 370 with mahle pistons which are these pistons http://www.summitracing.com/parts/MLE-LS1314030F04/

would i be safe with these heads?
what would that do to my cam selection?
will i be able to use pump gas?

pretty much i want to get schooled on any info you can help me out with!

thanks!
Santana

59.83 cc or somewhere around there...

I have a 6.0 with flattops or -3cc eye brows (4.005 bore). I run 91octane, 240s duration cam, nitrous, .055 head gasket (stock) puts my compression around 11.1:1

That would be 59-60cc chambers. You should be fine with those pistons. They have a -4cc relief so unless you are running some kind of crazy cam, PTV shouldn't be an issue.

It was on my buddies truck. .030 6.0, .030 milled 243 heads, patriot extreme springs, stock rockers, big converter, 4.56 gears. We tuned it on the street. I don't think he ever put it on the dyno. It ran real good though. Drove it daily, no bucking, 91 octane, 18-19mpg

Still has the same cam with .030 milled L92's and .040 Cometic head gaskets. It has a bum 4l60e trans with a stock converter in it for now, so no numbers or racing.

It's a stock crank, after market 6.125 rods, arp bolts.

My new motor will use a 4.030 diamond piston for use with a stock 6.098 rod. I have a set of LS2 rods I'm going to use
