those heads require a 4.125" minimum bore, your thinking of the small bore LS7 heads, which are not on the TSP website. I vote for the TSP small bore LS7 heads!! I wanna see what kind of numbers those heads produce on a 416-418 stroker.

I think a 4.070 bore and 4.100 stroke is a 427.
4.070 bore and 4.0 stroke is a 416.
4.080 bore and 4.0 stroke is a 418.

Yeah, it said a 4.0 stroke.

I still like the cathedral port heads. TFS or PI (Mast) 235 or 245. These are some proven heads.
I'd like to see some #'s on the TSP Small Bore LS7 Heads. They just hit the market.
TSP should put some of these heads on their 418 and get some #'s. They said these were the perfect head for a 418. So let's see.
