So….more header talk….this had me scratching my head

I agree totally. It’s all class/rule/budget dependent. To make the bold claim that all big ports are bad (referring to the original post made because that’s what the guy in the video said to him at the track) and all big cams are bad is simple minded thinking. And it doesn’t always apply.

It also begs the question what is a big port. And what is a big cam. Or a big header. Drawing a line in the sand on the definition of those things can put you in a box you can’t get out of.

Thats also exactly it. What is a big port? I guess we could say that a 225cc intake runner on a 300 or less sized engine is to big for the grocery getter car that mom drives unless she is as twisted as they get.

The same rod the reverse. What’s a small head?

I say let the dyno tell you and have a realization that even though the dyno says “WIN WIN”, it may not be a good thing in the street. Or even the track for that matter.

The biggest thing is the Knowledge of what works for what arena and how to do it best for your particular situation.
