I dont know about the intake flow #s. Its capable with a stock size valve but dont know about that pic, kinda hard to tell. But you cannot look at a port and know what it flows anyhow lol. The seat sizes look like 2.00/1.55

yeah they are the stock size valves, they have done a valve job to both intake and exhaust. other then the porting that's it. I was a little sceptical of the flow numbers but they look decent and the price is right!

yea i know i almost bought them my self exept that they dont come with the valves is just a blank set of heads, so the price u got wich is pretty good i saw them too, ad $100 + for valves $100 + for springs $100+ for retainers and those are some cheap *** parts i listed there, u still come out good but beware he has no actual flow sheet i asked him for one and he told me the machine din't make print outs, and the price he is giving those for is remarcable considering they flowing as good or better than afr heads, seems a little fisshi for me thats y i backed down but hey if u feel good go for but be carefull use paypal so u have a paiper trail. the story he gave as to why he is giving them so cheap should be easy to confirm, get ahold of that school phone number through yahoo, or 411, and call them and ask to talk to him if it is tue he'll be a teacher there and u could verify everything.

I would be cautious. I bought a used set of LS6 heads from a member on this board "Minty" that were suppost to be great. They were a POS! I should have bought a NEW set of AFR heads. They would have been cheaper and alot less of a headache! Watch out on those good deals. Good luck. Andy

Those are some very strong numbers. Especially for stock valves. Beware.

I agree. If it seems to good to be true; it is. Especially from a private seller. You have no way of knowing if it's no good or not until it's too late. Since used parts are sold "as-is" you will be screwed if the heads turn out to be junk.

If this person can't print out flow numbers I would run away from them. Even then you're still taking a big chance on the actual performance. Your call, but don't bitch about them if they suck.

well the guy said he works at a shool in texas and that one of his students did the heads, it should be easy enough to verify that part of the story. It won't tell us if the heads are good, but atleast we'll know if part of what he is saying is true wich would make the rest a little more credible, but those are still some damn good numbers, specially for the price, and no flow sheet thats what send me running in the first place.

I got a flow sheet. Unless you have a dog that isn't pottie trained my sheet wasn't worth ______! Flow the heads yourself. Mine were off 20-25 cfm! Also with many other problems. The heads could be great just be cautious.
