Intro to a port job

Looks like a lot of good potential for a street 318 with a heavy mill cut, 1.94/1.50 valve retrofit, and associated porting.
Honestly if I was doing a street 318... I would port a set of 318 heads. Beyond 375 hp is beyond 318 cid for "street".. build more cubes at that point is what I think about that. And putting a seat for a 1.50 exhaust in an LA 360 is not what I do...
I would just use a 318 head.. on a 318cid.
