A stock BBC is a 23* head..........and they would NOT roll them over unless it made a difference. Now, while I DO have my doubts about that HP number claimed for a 582 conventional headed motor, even with SR-20s, as others have stated, to build a Mopar, inch for inch and power for power with a stock TYPE head.............ain't gonna happen. That SR-20 is a killer head, but you put it on a .100 smaller bore and it will kick it in the head.............hence the 4.800 bore space of the Mopar is the root of most of our issues with killer heads Monte

The SR 20 is a legit 500 cfm head.You would have to use a hemi head if that rule is strictly inforced because I do not know of any wedge head with a stock valve angle that moves any where close to that much air. Predator should do it but not legal. Hemi would be the way to go. Not cheap. Todd www.mopartsracing.com

No way you could pay me to race a max effort hemi and keep up with it. A SR20 BBC would be 1/2 the upkeep. One day I will have something cool here.

I would think if the Hemi head would be legal so would the Big Chief & Big Duke heads and they still ain't the best chevy head!

It is futile to attempt to compete with a performance aftermarket that continually updates engine blocks and cylinder heads for race engines labeled Chevy and Ford, let alone the R & D provided by the top builders. If the parts don't exist for MOPAR racers, they don't exist. It's as simple as that. Face it, short of our "Pro Stock" hardware, like the P5, or the HEMI.......even current Pontiac block and head offerings from the aftermarket have surpassed MOPAR.

You could have three of the Chevy motors for the price of one hemi at that level. It can be done but I would advise against it. A lot of sanctioning bodies have rules that just are not optimal for the mopar stuff for sure. Especially the truck pullers. I just said it could be done but not it should be done. www.mopartsracing.com
