A small port like that flowing 233 cfm must of had fairly high average velocity.

When that job is all said and done, I’d love to know how many hours he invested in it………. And what the bill was

Whatever he’s charging it’s probably not enough

I agree.
It’s one of those situations where his overhead is pretty low, so he could charge well below market value……… but does he?

I’m pretty sure it is indeed a “side hustle”.
Crazy how many man hours have been poured into projects like this. Not just the guy porting these heads, but all the copycat misinformed guys that will be working their *** off only to get - at best - marginal improvements.
Some myths need to laid to rest. One is that 302 heads - and really - any LA heads - are worth messing with beyond the most basic cleanup work. Sure...debur the rough spots, do a rough port match, get the valve job sorted out correctly. That'll get the average joe results.
Another myth is that anything beyond really basic port work, done by the average joe, will yield good results. If I've learned anything at all on this forum it's that porting these heads really requires a flow bench, lots of experimentation, and experience.

I did a set of "302" heads a few years ago for a FABO member, and I did flow them when I was done, but the numbers were quite disappointing, I threw my notes away on those.
You don't need much more than a little common sense porting for improvements.
