DO NOT BUY THESE HEADS!!!! I bought a set and sent them back because they flowed like crap. OK... Here's the whole story about these Procomp heads. In a nut shell, they suck! I took them to have them flow benched, and to say they didn't come close to advertised numbers is an understatement. I took them to the same shop that have flowed other heads for me previously. They do alot of Pro Mod head work. How far off were they? Procomp claims 291/203 @ .600". These heads actually flowed 270/168 @ .600". The exhaust only flowed 174 @ .750"!. Max intake @ .700" was only 274! I was also told the valve job was terrible. The exhaust flow on these is actually WORSE than stock 241s. A 241 flows 198 @ .600" on the exhaust. These are going back and I'm sending my 241s to Lloyd Elliot. My advice is to stay away from this Procomp junk.

Too late I already order these 35mins ago...word of mouth means nothing without pics and a graph. So if these heads are junk... we're all going to see and I mean we're going to see these things cut in half and all of that.
The proof is in the pudding and I believe in performance on a budget. So I spent $749.00 for heads and 3 day UPS ground to TAMPA where I am. And next week we're all going to see what is the truth is with these heads.
For $699.00 I just had too purchase them hell if they flow 280+cfm I'll be a happy camper. If they flow 293cfm as advertise these are going to be everyone new favorite on a budget. And if they crap well then...everyone will know their crap because I'll post pics and the graphs to prove it.
Performance on a budget what I am about this day and age!

I'm not going to judge them on flow bench result. I wanna see the result on them on a car and a track time if possible. That's the number that matters. If this guy puts them on his car and they work who cares about the rest of the bs. Now if his stock heads work better then Lmfao. Let him chop them up and post all the pics he wants. Until someone uses them no one will no.

Look, folks. There's more to this story. I bought these heads with the hopes that they would be what they were advertised. I was arguementative in Procomps favor before I actually got them. Everyone used the term "cheap". I thought the same thing as many of you. "Just because they're cheaper, they might still be good." My fiancée owns her own performance parts store. She set up to be a distributor for Procomp when we bought these heads. That gave me 2 reasons to hope they were as advertised. Since she was going to be selling them, we took the heads to a reputable shop to flow them for us because she also wanted to know what she was selling. Needless to say, we were both disappointed when we got the results. We drove 2 hours to get these checked and I paid $110 to have them done.
My fiancée contacted Procomp about the differences in numbers, and pointed out that they were blatantly misrepresenting their product and they were guilty of false advertising. They are supposed to be changing their flow numbers in the EBAY ad. Apparently, the numbers on the ad are for their 2.055"-1.60" heads, that are $610 EACH, not the one's listed on EBAY. They told her they would refund the money.
Now, once somebody bolts a set of these paper weights on their engine and it runs like crap, they won't refund your money. You're going to waste $700.
We bought these things, wanting them to be as advertised, but the old saying is accurate..."It's too good to be true." Now our original 241s are on their way to Lloyd Elliot and my Fiancee is no longer selling Procomp heads.

Those flow numbers look fudge sorry but no way and trust those flow numbers @ .400 lift and above they look altered. They're 4.4% percent higher flow than LS6 Sorry i'm not buying it. Just like a health screen we're all getting a 2nd opinion. I'll post the flow numbers next week. We're going to see what is what if my factory LM4 heads flow better with a 3 angle valve job then okay. If these head flow better then okay. We're all going to see... if these heads are what they say they are....we have many flow shops in the tampa bay area so we're going to find out the truth. Matter of fact I suggest we all start calling out these companies that advertise high flow CFM and don't deliver. I'm sick of these companies ripping us off!
Next week! I'm shining light in someones hole $749.00 spent we're going to see!

Here are the facts "ShowVette."
These are the exact same heads www.HotRod.com tested in a LS1 Cylinder head shoot out.
And here is the link to prove it. http://www.hotrod.com/techarticles/e...t/viewall.html So scroll to test 6 on the page and look at the flow numbers of these heads they Flow tested themselves.
So either company you had flow tested these heads are fudging the numbers or HotRod.com is fudging numbers or ProComp is fudging the numbers.
And these heads aren't $699.00 each they are sold in a pair for $699.00 Clearly it states sold in a pair at the bottom of the page in big bold red fonts.

When I get these heads next week I'm doing a build thread I am going to have them professionally flowed and graphed. ...they're going on the engine no delay and I'm headed straight to the dyno in Lutz and put it on the rollers.
We are going to see if these Chinese sweat camp labor heads are what they say they are!!

These ARE NOT the same heads as Hot Rod used in their tests. This subject has been brought up in several other threads on this forum, alone. Not to mention the fact that my Fiancee was told point blank that they weren't. Look at the valve sizes. HR heads had 2.055" valves. EBAY heads have 2.02"s. Stop being hard headed and actually go to Procomps web page. The heads they have on their page are sold per head! Look at the price for a set of heads in the Hot Rod article. Sometimes it helps to pay attention to the facts and not try to make up your own. These EBAY heads are junk.

$610 PER HEAD for the heads on their site. They don't even sell the EBAY heads on their actual web page. The owner of Procomp even told us the EBAY flow numbers aren't correct for that set of heads. Are you not listening? Don't you understand? If these heads were what they were supposed to be, they would be going on our car! You think $749 is a good price shipped? We paid $590 shipped for the pair because she WAS a dealer for them. I would have certainly took a chance on a set of $550 heads if I thought they had ANY chance of making power.

This aint rocket science. Look at the specs on the Hot Rod heads. Look at the price. Now, pick up the phone and call the people who actually make the heads and tell them you want a price on THAT set. I guarantee you they won't be $699 a set... http://www.hotrod.com/techarticles/e...t/viewall.html
