If the rules just say 'Must use iron heads" you should be golden. If it says "stock iron head" nope. Any valve train specific rules? If not, offset rockers should be OK.

How heavy/fast is your turbo car? Unless it is stupid fast/heavy, 30 laps seems awful short for durability for a well built 904.

Just re-read your last post. I think you need a new trans guy. On the street IMHO the tires should slip before the trans ever does.
