You don't have to go up, but a 1050 or 1000HP would be worth about .010-.015 in ET. You have to decide if the money spent is worth the gain for you.

Sounds like you have some pretty good parts. I think you could bump the compression up. Get a good carb and fly...

I think a good 950 would be a need with the added upgrades.

SHOULD I HAVE THE HEADS MILLED TO GET 12.5 OR SO COMPRESSION THAT WOULD BE CHEAPER THAN BUYING NEW PISTONS CORRECT?

Yes this would be the cheapest way to go, just make sure you have plenty of piston to valve clerance.
