806 heads are they worth anything? I have been looking for a set of heads for my 98 and found some but they are 806 castings that have been P&P and the guy has flow numbers. I have no idea what they are supposed to flow but his reply was this....Heads complete with flow numbers 284 cfm intake and 193 exhaust @ 700 and 28 inches of water by Kim Barr Racing Engines and 806 casting number. Intake is 2.02 and 1.6 Exhaust.
I can get the heads all acc. broken block, starter, intake, maf, non stock cam, and he said that the motor made 510 with the heads and cam combo..... it is really a pretty much a pullout engine all included for 650.00 Looking to resell most to recoup some money but dont know if it is worth it.

Again you want numbers no higher than what the cam you are using because anything above that is as useless as using a condom with a girl after getting her prego.
Oh and the most important part that I forgot the 806 casting heads are perimeter bolt pattern not center bolt pattern so they will not work on the newer LS block engines unless you do the center bolt conversion and that is beyond me why would any one do that for those heads.

I appreciate the replys, I really want a good set of heads not so junkers. He is an hour away andc didnt want to waste the time driving if the entire setup was junk, I was just thinking of all the other parts that I was going to get. Raron let me know if you see anything pop up! Thanks, again

nobody is seeing this from the OP's position.
first off, 806 heads are just as good as any other LS1 head. the only draw back is the valve covers. these heads are going on a 98 so he already has the valve covers. no problem there. if they were going on a 99+ car, all he would have to do is change the valve covers to 98 style. actually a money making deal because the centerbolt VC's are more expensive than the perimeter bolt VC's.
