Ok so now we have a rough weight of say 3200lbs at the line and assuming a good chassis under it a 750hp TF270 headed motor should run 9.40's or thereabouts. If thats where you wanna be further down the road, then fine, build that with a big roller and 12:1+.

However if all you wanna do is run low 10's and stop there and not have to have all the extra Tech stuff, that can be done with a mild 10>10.5:1 620hp 512 that will run 10.0's with just a solid cam and probably with either of the heads you mention above.
