rules say no 300 horse heads, are 462's considered 300 hp heads? this is a bomber type class

My 492s came of a 275horse 327(had 1.94/1.5 valves). I think your tech man needs to be much more specific.

I think maybe you could get by with 993's there a good flowing head with under 300hp if they dont look, go for 487's or 441's stay away from the 882's.

What? Your running bowties, I have the small cammelbacks. Smartas$.
Seriously though your tech man needs a different method for choosing what heads you can run. If nothing else just tell them that they are 350 horse heads. then they should be legal right?

Cammelhumps are a good head but you need too get your self a set of VORTEC heads, you will need a new intake. I ran them one year got 9 feature wins and a point cham. But after that they outlawed them. You will know the differance in power.

ill bet if you ask em they will tell ya you cant run 461, 462, 291, 461x, 041, 492, or vortecs. no 300horse heads usally means nothing but open chamber "smog" heads. 441 best, 487x second best, 993, 624, 882, (ive heard they crack worse than others) etc. im not trying to sound like i know it all, but thats the way it is here. the rules say NO 300 HP heads, but they mean nothing but open chamber stock production, sraight plug heads.
