General Cylinder Head Flow Numbers discussion

Hi All,

I'd like to keep this discussion as general as possible to encourage dialogue on the topic. If you're open to disclosing specifics that is totally up to you, but I feel like there are probably a few opinions on this topic and it could be a bit of an interesting discussion.

Basic question here is when you have your heads done or you do them yourself in legal stock eliminator form (whatever that means in this day and age to you individually) what is the most important improvement in flow characteristics you are looking for? 80-90% of us have less than .500 lift, so are you looking to see the numbers from .400-500 to jump? Are you looking at port velocity? are you looking at average from specific lift values? something else?

This isn't really a discussion on "HOW TO GET THERE" but more with your end results compared to where the heads started stock what makes you decide the heads are going to make you .800 .900 1.00 under capable verse the stock castings?
