SM Head Modifications on a budget

I understand the goal is 280+ by employing a process that minimizes any more rework of the SSR than necessary.
My thinking at this point is……..you’re going to have to uncover a fairly significant problem area that yields healthy gains………that don’t keep the port from being so dependent on a better SSR.
As I see it at this point of the development………it’s still all about the SSR.

It’s very reminiscent of my earlier exploits with 906 heads.
