I thought about going with Williams Performance after following them for a while on IG, but their google reviews deferred my decision. I’m big on customer reviews, and I didn’t want to gamble.MSD Infusion, Monster Singles +3TB, 11:1 Piston stock bored and stock stroke, +1 newer model head with VP 105, like i said. I get 75 with no issues, you should be good. I'd assume 80+. My head was build by Williams Performance, since Cuervo had a 4 month backorder delay.
