It appears to me, the rockers have to be the same configuration as stock ie; a Mopar small (early) and big block must still run the same shaft configuration, but the needle bearing roller tip rockers are allowed, must be same ratio as blueprint specs. I don't think NHRA intent is to allow machining the top of the head for T & D, Jessel, or such. I think the intent is a stud mount must still be a stud mount, a shaft must remain a stock shaft location. Some people will be affected in that the specs might call for a 1.5, and of course there are usually no numbers on the stamped steel or ductile iron(Mopar), and almost all of the aftermarket has the ratio on them. Might affect camshaft etc, and is very easy to look at by Tech Inspectors. That is what got me pitched earlier. Cam checked, but the specs say 1.6 and I had 1.65 and I went home. That's my story and I'm sticking to it.
