I am just wondering about valve clearance. i am looking at a set of twisted heads with 1.7 ratio rockers. I have had the engine rebuilt with an e303 cam.

PTV is going to be very tight with TFS heads and 0.529" of valve lift from the E cam/1.7 rocker combo, so you'll definitely need to check it.

First mistake was going with the e cam, but i think it's gonna be really tight if it doesnt hit.

with 1.7 rockers it is , only way to know for sure is to clay the piston and measure it , but I would say its probably NOT going to clear from my experience
