Well gee..........if I were to choose between one of those 5 sets of heads on an identical short block, wouldn't the one that dynoed the highest make the most rwhp if it were going into my car? Or do you think that somehow the dart headed 383 would somehow get more power to the wheels even though it was down 40hp from the AFR headed one?

You always come in here with the same rhetoric over and over and over. Go look at the fastest LT1's and tell me what they run? Don't quote some stupid b-body cop car 87 octane stock shortblock, stock pcm, full weight record either. Yes there are some fast Ai cars out there, no question, but most of the fastest LT1 guys run AFR 227's and i'm sure you'll be hearing about some 235's out there now, not to mention converted 18 and 15 degree stuff.

Anyone with half a clue knows that highest rwhp is NOT necessarily the fastest.

"it is not how fast a car is, but whether it is faster than it should be that counts"

IMO some of the fastest cars would be faster with a little more knowledge in place of some of the coin spent.

At the AFR site there said that these heads where made for LT-4 intake manifold, does that mean that you can't use like an Old Eddy Victor single plane with these heads, like you can with old Lt1 heads ?

My god are you serious here? Did you read the link that I posted at all? It was test between 5 sets of 195-200cc heads. The AFR street 195cc set made more power than all of the others, some by a huge margin. Do you think that if someone would be in the market for a 195cc head that this would be a valid comparison for them to see? Or do you think that by some miracle one of the poorer performing heads could somehow deliver more rwhp and better track times?

You sure they make a 195 race version now? I know for the 180's and 195's they offer street and comp, but in 210's and 227's, it's only race and comp versions. I can't even find a 195 race version on the AFR website. Maybe you have a non-eliminator set?

The race ported heads are in between street and comp but actually much closer to the comp numbers.

The Comp ported versions are the top dogs of each.

Upgraded my MTI 396 LT1 last year with the AFR 195CC eliminator competition heads in my '94 Corvette six speed.

Had TPIS LT1 ported heads on the car prior to the upgrade for 10 years. TPIS flow sheets showed 255CFM intake /188CFM Exhaust at 600 lift. The car dyno'd 400 RWHP/415RWTQ. Mainly race in the TMCCC bracket series in the pro class. My dial in was usually 7.6 1/8 and 11.7 in the 1/4 with MPH being 94-96 on 1/8 track and 120-122 MPH on 1/4 track. Consistent 1.72-1.75 60' times.

After the AFR 195CC heads and lloyd Elliott porting my LT1 intake the car now dyno's 440RWHP/440RWTQ with a mail order tune by Moe Bailey. Expect to be at 455-460RWHP after a dyno tune by Moe.

Now dial in 7.4 1/8 and 11.5 1/4 but seem to have alittle more wiggle room and do not have to get low 1.7 60' to get my dial in. MPH is now 96-99 1/8 mile and 122-125MPH 1/4.
