$$$$$ that"s why. There are 5% on here looking for max performance. Most are street/strip cars or stock restored cars. E heads been around so long and so many miles some are just probably worn out!!!!! no other aluminum head can say that.

The E head will always and forever be the most popular aftermarket aluminum Pontiac head. Any other head does not have the slightest chance of beating them. Even if you did not count the E heads sold in the past, just the ones sold from here on out the E head will be the most popular by a wide margin. Maybe your sucking up will work. But here is the problem. Even if you get a great deal on RAV heads it will be VERY expensive. New expensive cam, intake AND headers. For performance use, they need to prove they are a step up from the less expensive heads. E heads, High Ports, Super Wedges and Tigers. Cv-1s (thats easy) More NA performance, NA is KING. Even beating the E head record of 1200HP will be a tall order. It will be tough, there is a obstruction in the port. Danny E has a shot at making good power, lets see how he does. But the heads do need to prove, money wise that they can straight up beat a standard inline head. Otherwise they are a very nostalgic, cool part that makes very good power, just not the most. Thats not a bad thing. Now if you want to talk real boosted power, the Wilcox RAV heads are the ones. They have made FAR more more power than Chief has ever made. Or anyone else. Its a true Pontiac race head. Nothing nostalgic about it, just a straight up inline valve Pontiac RACE head. |

RA5 expensive ............"I don't think so Tim" ........anyone (that is stepping up) and buying a set of 370cfm of larger heads will need to buy another set of large tube headers (no one starts off with 2 1/4" primarys), a larger camshaft (to take advantage of the better flowing heads) and a better intake (P4B just aint going to work)! LOL DCI RA5 heads as cast start off at 380 CFM with standard rockers (no rocker shaft needed) can't do that with e-heads! So all that BS you and your TWIN over on the PZ web site is just smoke & mirrors, all those items will have to be bought no matter what performance heads a racer steps up to! NOW as for those H & M heads (that no one has) who wants to mortgage their house when there are other performance heads that will go 500+cfm (Warp, DCI RA5, etc.) that are FAR more affordable........just saying!

The point is, while cool the heads do cost 5K. Then the special one off intake, special cam and headers are expensive. You can buy a set of std pushrod E heads from Wilcox for 3300$ that go 374cfm ! A lot of Pontiac performance guys have 2" round port headers and Victors in their garage. Used std Pontiac rollers are not hard to find. You can make real power with the above stuff for not a whole lot of dollars. That is a real option for some, its a smart move. They(RAVs) have to beat the pants off it to make it worth the extra dollars. Not saying they cant beat the pants off them. Now the H&M RAVs not cheap, but the real deal is often not cheap. What are you going to say when a Pontiac NA door car goes 6s. Or the new billet block one sets the all time Pontiac record. Warps, whatever. They are far from cheap. Have their own issues, canted valves on a Pontiac blocks is not easy. Still a BBC head on a Pontiac, whats cool about that. |

It did happen, some of the same people involved this time. Have a track record of making big Pontiac power. I know things you dont about it. Have some cad drawings I would like to share but do not have the OK. Its pretty cool to say the least. Dave will get all the pub when it happens. Scott, you should know of all people who have manufacturers turn their backs on you when their stuff does not live up. |
