for only adding heads and no tuning? running completely stock everything. what are you comparing this against? are there other cars that have put heads on a completely stock car to see what happens? can you post links to those cars if you have them? that way i can compare also? i thought .6 and 5 mph was pretty good for only adding heads and no tuning.

thats pretty good, altho i don't understand why someone would pay for $2300 heads w/o having a cam and all supporting mods. unless they're gettin 'em free just for the test.

The gains are what you have to look at. Althought he numbers seem low, the car did pick up 40 rwhp on a stock car. The numbers should increase alot with the addition of some good exaust. The car is probablly choking on it's own exaust now. Remeber vette's aren't dyno queens either. Although I would be ticked if my car only put out 279 rwhp stock. Would this happen to have been a Mustang dyno?

there was a point to testing just the heads only. man a gain of 40 rwhp with everything else completely stock is really good. any other head out that can do that on a completely stock car? if you read on about testing, they've since added the intake, headers and exhaust.

Thats a good gain for heads being the only mod. You still dont see too many LS1s make less then 290rwhp stock though. By the way HAPPY NEW YEAR and see you at the track in a couple weeks.

That is a real nice gain!
But, I would of liked to see a comprison using the same tuning perameters on both setups except whatever fueling changes needed to get the same AFR for both tests. Meaning the heads alone didn't generate the whole 40 RWHP IMO, but even if it was 30 RWHP, it would still be a nice gain...

Man 40rw hp extra on a dead standard engine is great, just shows how goods these heads are.
Normally a small stock cam, heads only wont make much improvement unless you loose low end for your top end but these AFR's are great and with any cam upgrade the HP would be crazy, even a nice 224 cam and you would hit big numbers without it be crazy.
Good work all involved. I think LS6 head comparison would only give 10-15rw hp over LS1 heads on a stocker so AFR u done it again.
