my recommendation .... either talk to a cam dude like ed curtis or jay allen for a combo, or just be done with it and get a total trick flow package that includes the heads, cam and intake.

Back when I was big into these cars, the heads you wanted were the trick flow twisted wedge heads. These days it seems to have switched to a brand I haven't heard of until recently: AFR. Are the AFR street heads the ones I want to get? If so, is there any particular reason why? I assume they just flow better than the trick flows. Trick flow used to claim 73 more HP than stock, if you added an appropriate intake, cam, and throttle body. They were saying that an exta 73 HP to that setup was JUST from their twisted wedge street heads. That was supposed to be minus all the power that the other stuff was going to give you.
So, can AFR make the same claim? Are they really better than the trick flow twiested wedge street heads?

This will likely be the route I take as well. Their top end kit is built with top notch and more importantly well match components. Combine them with decent intake and exhaust components and you've got yourself an honest to goodness 350hp contender. More if you add a little displacement to your engine first.
....and they look bad ass with the crinkle black intake manifold and valve covers.
Would it be worth port matching everything first? And when you say 350HP, you mean 350 RWHP right?
I would just bolt them on and go. Don’t' bother with port matching them. They're component match already and the Trick Flow stuff is pretty high quality, so you don't get a lot of the casting shift you would with other brands.
I disagree with this statement. Amateurs bolt on heads out of the box. Having the right person go through the head isn't that expensive and is worth every penny. Any head out of the box, even the trick flow, should get at least get a valve job. Once they have been dissasembled to do the valve job, touching up the port work is inexpensive. My engine builder port matched both my heads for $65.

Don't get all tied up in catch phrases like CNC machined. A lot of the head and engine factories push the term. What it really means is they set up the machine once, and then pay an unscaled worker $10/hr to feed it blocks and heads.

Monkey or no, the results speak for themselves... just saying.
One other thing, I would expect a built 347 to bust off 11.5's without nitrous.
And we appreciate the advice Kurt.. it's always nice to have people warn us about mistakes like that. All the more reason I want boost because frankly I don't like messing around with heads, cams, intakes, etc... there's enough different combos to make my head spin!
