With the new cylinder head rules (aluminum) If I were to build a GT/KA engine and use Aluminum heads (AFR) Would I have to cut the valve down to the correct size or do the rules allow out of the box use? Also with the difference in CC's of the heads can they be milled to the factory numbers? Is it worth using aluminum or stock style heads having to add the weight for aluminum? Thinking of building a 1968 J code 302 engine for SS racing.

Any info would be helpful. Thanks in Advance.
