Ported X head pics

You can lay an x head back a ton more than a j head fwiw. J head hits water sooner in the ssr nearest the straight/common wall.
It looks similar to a laid back 318 short turn once in the 270's range. Hint.
thing is. .. if you dont know what you're doing you can damage the .200-.350 flow beyond what I'd call acceptable. Remembering that the valve job and throat size% is siamesely connected to the lower .100-.400 performance is important .
