what heads to use

I need some opions on what heads to use on my 347, I have a fresh set of 68 closed chambered heads, but thinking I might what to go with alum. trick flow heads? by the way the blockis a 91 5.0 and its going into my 65 falcon

Well it depends on what your doing with it. Give us some more info, like pumpgas, race gas, compression, power you want, etc....

I would like to have it set up for the strip mostly run race gas and nitrous, not sure about compression ? thanks for your help

We sell trickflow heads, and I can tell you the cnc ported TW heads produce very good power.
I know the afr's do too, but I like Tooleys work and he's got a ton of championships under his belt. It's his cnc work that TF uses.
I would say you need an rpm range, and then pick the head that will work in that range. Start there...

NO ONE beats AFR for the most bang for the buck ( dollar )I have made 649 HP with out of the box AFR 205 heads on a 347 engine. That is HARD to beat.

Is that right out of the box, or with some work?

I believe he just stated the AFR205's were right out of the box...must of been a big cam making that power. Would of loved to hear that thing rumble.

We are a little off base here. The cam was a custom grind, like 268-276-700 lift, HP peak was at 7500 RPM, Funnelwen, 1050 carb.12.75 to one, 1 & 7/8 headers. The heads were untouched, except cut for bigger sprrings, Jesel shaft rockers.I reved it up to 8000 RPM, sounded goood.
