318 head porting for the average joe

I have a set of 302 heads here on the shelf fresh from the machine shop (ok 3 years ago but still not mounted on an engine) and yes I plan to pull them apart this summer and clean them up, mostly just casting flaws and yes I'm gonna RUN THEM... On a 318, even.
Tough. Not going speed master, not yanking my 318s for 360s, nothing of the sort.

Ok let the boo birds chime in.... Too bad it's what I'm doing.
And I have a 2nd set of these heads to get thru the machine shop so I can do the same thing to them.... They're what I have, and they're what I'm gonna use....... Can't be any worse than the 163 heads I have now..... (These 163s are original to my engines)
Don't have the money for speed master and wouldn't want them if I did because I am trying to keep the chinesium content as close to non-existent as humanly possible.
If I had the money for aluminum id probably buy the Eddie's.
