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

THANK YOU for responding. So far you are the only one! I had figured on getting ahold of someone at NHRA before I purchsaed parts because I know what you are saying about that. I guess I was just asking in general if you can use aftermarket heads and blocks? Thanks for your input.

To answer your question YES you can use aftermarket parts-----Which parts will be accepted I do not know!!!!!! You will have to get an OK from NHRA Tech Dept as to which or what head/ block whatever for a FORD in Super Stock will be acceptable---- Basically it must be OEM Factory stuff but they do give you a little leeway as long as their is no performance advantage over the factory astuff--- By that I mean it can be a more durable piece more heavy duty like 4 bolt main block vs. 2 bolt , but no performance advantage. Like more HORSEPOWER !!!!!!! Comp 387

Ah, I see. Another gentleman on the S/SS board says I can not run aftermarket heads, Ford OEM only, so now I'm really confused. He mentions the GM guys can use certain Bowtie parts though so I wonder if any Ford Racing parts would be acceptable? I'm just going to have to bite the bullet and contact NHRA I imagine. Thanks for your help.

I asked NHRA the same question a couple of years age. I can't remember the exact answer but they did consider FRP heads to be OEM and legal.

But do ask NHRA because rule interpretations seem to change over time.

Thanks, a call to NHRA is in order.
