In modern NHRA STOCK CLASS, 302 &amp; 305 Heads are so exotic that the valves are relocated, cantilevered and the heads cut in 1/4's , relocated &amp; raised ports, rewelded etc, etc, etc......its common to have $18 - $ 22,000 + in heads and intake work. </div></div>

Um, no.
In Stock Class, heads are stock, with stock valve sizes in their stock locations and unported.
You can have a 3 angle valve job using any angles.
