Your best bet is to get together all of the part numbers and a description of any parts you are thinking of using and send a letter off to NHRA Tech Dept. in Calif. and ask them if a specific head/block whatever is OK to use for that class BEFORE you purchase any parts. I would also enclose a self addressed stamped envelope so that you can get a written answer by return mail.---You also can contact your division tech guy and see if he can give you an answer too but overall Calif. has the final say on what is OK---Comp 387
