Thanks, that's exactly the commentary I was looking for. Appreciate that.
I have definitely seen some crazy looking W2 ports. Very large rectangular ports. It's actually pretty wild how much can be carved out of these. But that's not the realm I was interested in. Definitely cool, but way beyond what would be reasonable to invest in a set of cast iron heads, unless you happened upon them, already modified.
Pretty cool that ootb heads can essentially be pocket ported to 600 hp capability.
