Well said. Stages are relative from company to company. Our stage II heads will be the other guy's stage 2.5. So the best thing to do is get the specs on valve sizes, runner sizes, etc. and go from there.

Precisely. All that "stage" BS is just that: BS. I laughed at the ricers when they started doing it and cried for the domestics when they started doing it. Stage 11ty-billion doesn't tell me squat. Give me verifiable specs.

I agree...I would much rather have the facts laid out in front of me instead of telling me I would have a "Stage 93 car". I understand it distinguishes different packages from a certain company, but it is such a vague description. I often make myself "wish lists" for my car and find these different stages as options I could perform. Now if I only knew what that was...

Usually stage 1 means ported heads with stock valves. Stage 2 means ported with bigger valves and stage 3 usually means ported with bigger valves and the combustion chamber has been opend up for big bore engines.
Every company is different though.
