Best heads for my set up?
That dyno sheet seems to really take off after 3k rpms. I cant tell the rpms but from where the Tq/HP meet and judging it off that which would be 5252, looks to be around 3k rpms.
This was a 6 speed car. We weren't very aggressive with the timing on the tune mainly because it was 99* the day it was tuned, nearly 80% humidity and the DA was hovering around 3000 so we left some timing out of it that could of made some more power and we left it at 13.0 AFR for the most part.
We told the customer if he wanted to really put down a number to bring it back in October or November and we would put the timing back to 28* and lean it out a few tenths and put that 475rwhp number up on the board. I have no doubt that with an electric water pump and a ported Fast 102 it would of made 480 at the tire in the heat and over 490 in the cool?

Alright. I've got a LS1 pulled out of an 02 vette and it's got the 806 heads. My engine is being rebuilt right now with a few of upgrades; MS3 cam w/112LSA, Yank PT4000 converter, PRC .650 dual vale springs w/titanium retainers, seals and seats, TSP Hardened pushrods, SLP Double Roller timing chain, SLP ported oil pump, TCI flex plate, Comp lifters kit, LS6 intake, BBK 85mm throttle body, Taylor Cable TB spacer, SLP Flowpac intake package(whisper lid, smooth bellow, forced induction, K&N filter), headman headdress, 3"pacesetter performance off-road Y pipe, 3"cut-out, SLP Loudmouth ll exhaust, 3:73 gears, Jet performance mass airflow sensor...aaaand a fully rebuilt 4L60e.

Im a trick flow 220cc/polluter owner. I wouldn't personaly consider anything but trick flow after my experience. You get what you pay for.....
An after market head has lots of benifits. Including HP's.. Nothing is worse than sitting there after that first test drive and knowing you left a good bit on the table
Its only money, imo....

Its only money, imo....That was through a M6 FWIW and it was HOT outside and HUMID! 98* and nearly 80% so we had to back off of the tune AFR wise and timing wise to keep it safe.
I'm completely sure it would make 475+ in the cooler fall months with a slightly leaner AFR and 1-2* more timing.
