FRPP and MAC work well both in shortie config, mac makes a BEAUTIFUL set of long tubes for the P & of course work on the rest of the reg. exh port sbf heads
anybody know if you can still get the gt40p heads new & drilled for smog or anybody who would drill ANY heads for smog? central coast mustangs used to sell them new & drilled but I think that company has been gone for some time.

RE: gt40p heads?
what exactly are you asking? If you are asking if you can cut the GT40P's intake valve seat to accept a 2.02" valve, you must understand that even if it could fit, which it does not, that head has quite small ports: that valve might not be very useful..... I dont think that a 2.02 valve will fit in regular produtions iron ford sbf pushrod heads at all. Hopefully someone will correct me if wrong.
The point of these heads is not to go max valve max port, they are a restrictive port design. It sounds like you might not be happy with these heads at any cost. Perhaps you could turn around and sell them for a profit and get some big ol brodix heads or something on that magnitude[8D]
