(I never said anything about ported vs non ported.
You cant allow aluminum heads (or champion irons?) if you're looking for a 12-10.5 second class. )
Please help me understand how to keep " champion iron" heads out of a class without any disassembly to verify? That would kill tech, making it difficult.
A lot of street cars have aluminum heads so that is one rule I struggle with but was trying to allow?
