I got the feeling that just any iron heads wont be the deal. But they needed to have something to help the Chevrolet guys as they were cracking heads in short order. Knowing what these engines can break, I would not wish that on anybody. While I am concerned we all know that port volume or cfm do not only make the HP, I have worked an awful lot of stuff to find .07 over the year, so I cant imagine we will be obsolete, YET. Bruce and the NHRA seem to be aware of how touchy this is. The good thing is that there should be more trying out the SS/CS water, I can attest to the warmth (DAMN near boiling!). My biggest fear is that the class dwindles to 5 or 6 cars then gets written off.

Vince, I was told a complete different story and that ANY aftermarket cast iron head will be allowed. Was also told that the GM LS cast iron 1999-2000, 6.0L,OEM truck 873 casting cylinder head was approved. This cast iron head, untouched, already has 210cc intake runner volume with a 2.0" intake valve. Add bigger valves and some extensive porting, they will flow 360+ CFM's.

If any of the Ford racers are interested, I know were a pair of brand new untouched RHS Ford, 20 degree cast iron cylinder heads with 225cc intake volume heads and 57cc chambers, are located.

After 15 years of lobbying NHRA for head studs they finally did it......

No more Heli-Coils in 40 year old blocks.......

Thanks to NHRA...Better late than never........

Its VENICE,

The rule does not say ANY, it says aftermarket, and I specifically asked about rolled over and Australian pro action stuff when I talked with Bruce. That is not the intent. NHRA always has to have something aftermarket on the approved list, so far there are only two. My only concern is that as a class competitor we were not asked our opinion. Nonetheless it would not be wise to start a cylinder head program for one of these cars without making sure the castings are legit. There is no proof that either of those heads are going to ruin my combo, and if it makes more people think they can do it easier I am all for that. I will take Bruce on his word before i would build an engine on hearsay. DO YOU run CS? If so you should put your name on your posts. I am sure Bogner, Menard (RWR). Hudson, Antonette, Mans, Groves et-al ( sorry if I missed anyone) know what it takes to go fast in this class. The heads are just one piece of the puzzle. Its really easy to put one of these together, bring it on out!

So, if a car running in one of the FS classes is the only one in their class at a National event where class wins are contested, will they be folded into the combo with non FS stock eliminator cars or will FS cars have their own combo?
