OH YEAH, it has to LOOK "Stock". ;-) Well ya know? I just re-read the rule book any YOU are correct! You are however allowed to CNC port the intake/exhaust runners and the combustion chambers! If you're running a FS car. Now that hardly seems "fair"!

Re: U/SA 302 ffffford build
4th sentence says “must retain stock diameter and angle + - 1*”. But the 4th sentence from the bottom says “any valve job accepted”?
Well i did 4 angles (cant find my 75* ) 15 in the chamber, 30 below that, 45 seat and 60* in the throat. Im pulling my hair out because the flash and casting crap as well as the lip left from the 15 cut is killing flow but i cant legally remove it. Stock casting SUCK!! Lol! So much easier to make power when you blend, lol.

Re: U/SA 302 ffffford build
You can use a radiused cutter. That's not illegal.

Re: U/SA 302 ffffford build
Stock valve angle in a small block Ford is 20 degree VALVE angle - relative to the deck/cylinder head surface. ANY valve and seat angle(s) for a valve job are permitted.

Re: U/SA 302 ffffford build
Just got in from the garage and wow, I kicked over a hornets nest! All good though, it'll be clarity for the next guy with a seat cutter and rules comprehension phobia!
gotta go, but today I finished the heads, put light springs on for break in and no valve seals. When it's broke in and I'm putting the big springs in, I'll put some seals on the intakes as well.

Don't get carried away with your valve spring pressures!
