Making power out of the 318

Well I happen to have 2 sets of 302 heads, one of which is fresh from the machine shop, and I will be putting them on one of my 318s whether the rest of the band here "likes it or not" because I have them and I don't have anything else. And no $$$ for anything else.
Not a fan of speed master heads anyway myself, as I try not to use china parts when possible.
Plus all the talk about having to spend the money for them and then having to send them thru a machine shop anyway, like I would if I had any old set of heads ....
Like the last set of EQ heads I bought. Supposed to be ready to run out of the box.
Within 6 miles those "ready to run" heads stuck a valve and it kissed the piston. 6 miles. And they had to have a valve job.
I'll take my chances with the 302s... In my case I have 163 heads on my engine, (original for the 78 motor they're on) it ain't gonna be any worse than it is now...
