Was just looking at the new NHRA 2020 Rule Book amendment prohibiting spacers between the intake and the cylinder head.

They already allow sheet metal intakes and also two piece intake manifolds split in the middle in the class so what is the difference in having a spacer between the intake and cylinder head?

This will effect many cars including Mopar 383 with Chevy intakes, Ford FE with 351C intakes and AMC with Mopar intakes running spacers to fit these intakes.
