Are 416 heads a TPI head? I think about getting some for my LO3

416's are older style heads, same thing as tpi heads, just perimeter valve covers, and center intake bolts arnt angled like the 87-up. The came on LG4 and L69's.

If you can find 305 TPI (081) heads from 87 on up I would go for those. They are the same head as the 416 but are more of a direct bolt on. You can usually get them for the same price but aren't quite as available as the 416's.

I have the 416 heads and my advice is to get the 081's.
