i hope you have aftermarkit pistons and not stock replacements, that big of a lift it will hit pistons.

If it doesn't go 6.30's there's something wrong with it. :D Although, in my opinion, the heads are too big. Still should go better than 6.90's. Lee

In my opinion, yes. Or even a set of Dart 320's maybe. Mine has 290cc heads with 2.19 1.88 valves, 850 carb, bigger cam (lift), less compression, and has been 6.43 (1/8th) and 10.17 (1/4). Lee

Heads are too big. I ran a set of Dart 325's on my 468 that had a little more cam in it and it didn't pick up much over the 781's. More I think because of weight. I always thought my combo would have been better suited by some bmf 310's or afr 305/315's.

Heads may be too big but they may kill enough bottom end to hook the thing. You've got a small tire, a lot of gear, and a 2.48 first gear ratio. Start saving for a glide! The engine combo sounds pretty stout. Like others said--if it hooks you should be 6.40 or better.
