pretty good, those are the same heads im looking at getting.
what kinda exhaust are you running?
looks like you could of ran it up another 200-300 rpms, and might of gained a higher peak #..... its also hard to read the a/f, kinda looks like its at 12.5 though towards the end, mgiht be a few more poneis if it were closer to 13 or low 13's. good deal though, bad *** to have a 440 rwhp all motor beast!

how much are those heads milled and how much flycutting was required - i wouldn't think you could mill .030 and run an MS3

my heads were milled 30ths & it's 5.3 liter heads-- i have mahle forged pistons with -2 cc valve relief and i used 6.125 H beam rods. i don't have a problem with valve clearance - because i already had 2,000 miles on the engine & it was still running great
i also am posting my air flow ratio print out- i will try to get the ported tb & lean it out just a little bit - then i will check the dyno again.

Should be higher than 440 rwhp. With the PRC 2.5s only giving you a gain of about 20 rwhp over cam only cars with the MS3 and 10 bolt, they aren't very impressive. It's probably just the tune though. Take Gomer's advice, lean it out a little and twist it up to about 6,800.
