Im on the last step of my engine build and im left to do the heads. im replacing the stock multi piece valves with some stainless steel ones. my question is what valve sizes do you guys use? should i stay with stock sizes or go bigger?? thanks also my machine shop guy is doing a 3 angle valve job.

Stock size is fine for anything up to some fairly large horsepower numbers

MMMM, do you have 2v or 4v heads? A normal thing that us blokes down under do with 2v heads is to use a 2v intake valve and a 4v exhaust valve, and have the heads properly ported by someone who knows clevo's, 400hp no worries...

Heads are 2v
