I SENT THEM TO DUANE PORTER LAST YEAR. That is the right guy to send them to. If Dwayne did the heads then you should be ready to go. He'll probably have a record of what the combustion chamber size is too and he can provide you with a cam recommendation if you don't already have a cam. Do you have a Stage VI intake? If so, 4150 or 4500? You'll need a 4500 intake and carb to make the bigger power.

well, if you don't have a stage VI RB intake manifold, one just got posted in the race parts section here... If it's the 4500 piece, that intake along with a 1050 really woke my 498 mech cam StageVI junk up.

You don't need a big stroker to run in the high 9's

Any idea what the typical DA is where you race?
And for those keeping score....... I didn’t port Ricks heads...... I repaired them. They were suffering from the “not all that ususual for stage 6’s, the valve seats are loose syndrome”.
They’re std port stage 6’s with similar flow numbers to BradH’s old 6’s.
I’d probably lean towards to low deck 511 build myself. The 400 block is generally tougher and that combo can use a std RB intake manifold.
Flat tops .005 down the hole and .040 gaskets, heads at 72-73cc, would put it at right about 12.5:1cr.
I’d probably open the heads to MW size and run either an Indy 440-3 or the Edelbrock SV.
Put enough cam in it, should work pretty well.
That being said....... if it were in the budget, better flowing heads wouldn’t be a bad thing.

You don't need a big stroker to run in the high 9's Given what your old car in your signature ran, I think you'd agree that you don't need a stroker at all to run high 9s. A well-built 440/451 can do it with the right car combination, but it's not the way most people choose to go about it these days.

According to my no's in a 3300lb all in car you only need 672fwhp on track to run S/G times@135mph.....Moroso s/rule will show even less. You don't need 500+ cubes to do it, 440/451 as said, put some decent gears in it (4.56+), and let it 60 and rev through the traps. 7k+
1969 'Cuda 446ci, best 9.96@133.9 in 1990 1971 340 'Cuda, best 11.01@122.8 in 1987

A build like this should easily make 1.25ft/lb per ci.
You have to buy a crank, rods, and pistons anyway...... the extra cubes are free. I’ll take the extra 80ft/lbs of torque for no additional charge please.
The Moroso chart shows 650hp for a 9.80@3300lbs. I’d be targeting a solid 10%+ over that to account for a less that optimal chassis set up and air quality/density.

Just lose 500 pounds and do it with 906 heads, stock rods and crank, TRW pistons, and old school technology like we did 30 plus years ago. You guys are spoiled. Lol 😂
