Better acceleration?

I have to say I've been really enjoying the discussion going on in this thread. I wasn't really sure what to expect when I posted up asking for advice but the replies have been great. I'm no mechanic (I'm more of a driver but am putting feelers out locally for somebody to learn from) so a lot of this stuff is way over my head, but I do know how to learn so I've been hitting the Slant6 Forum and Google to help me decode what y'all are talking about. Regarding my engine, it's a rebuilt mid 70's with a bigger cam (I still don't know if it's been degreed but I think so given the rep of my mechanic) with about 1000 miles on it. The head was milled about .1 but it hasn't been ported. I'm pretty sure the pistons, rods and stuff are all stock. I'm taking it in to the shop next week and they're going to give it a look over, fix some electical stuff, and among other things install a rebuilt distributor I got from @halifaxhops that I'm hopeful will improve response time and acceleration. Given what I've been learning here I think my most accessable path right now is to head up the freeway to Wildcat Auto and pick up a new head that I can hopefully find someone to show me how to port out, and get some larger valves. This car is my daily driver and I don't want to lose it for weeks or months while the work gets done on the head that's in it, since I'll probably be relying on the mechanic to do the teardown and buildup. Second step when the money comes in probably should be pistons, rods and rings, right? And some day, when my ship really comes in, a Torquestorm and a rear end to go with it. Hell, a guy can dream....
