Cathedral or Square Port heads on 408 stroker I havent found alot of info on which heads would be best for my setup. Want the best bang for the buck whether its cathedral or square port heads for boost, TFS,MAST,AFR etc etc...
Engine is Going to be a 408 stroker with 9:5 or 10:1 compression with twin 67s...Planning on making 1000+whp...Just want the right head for my setup/goal. Thanks guys.

well you just named about the three best options out there....so I assume you must have a pretty decent budget to work with. Most NA applications seem to like the port velocity of a well done cathedral but since your snails will be cramming the air in there, the cylinder head will work no matter what.
The after market heads you mentioned will all benefit from a fancy and expensive rocker arm set up because of the bronze valve guides...so a true bang for buck head would be the CNC GM LS3 heads at just over a grand new. Swap the springs and go. Or if you can find a low mileage used set from the Vette Forums, I'd send them to Tony Mamo for an exhaust runner make over along with a quality valve job and some minor chamber work. Give him a call and see if he'd be willing to tackle that as he no longer works @ AFR....so he seems to be working on all sorts of neat stuff these days.

Given your horsepower goals and the fact that you are forced induction, I would say square ports. I'm sure Tony has some magical mamofied AFR heads that will do quite well for you

Thanks guys, ive really been thinking about the square port heads but some say that they arent really good for boost since the exhaust flows less then the cathedral head...this is just what i have seen through research... Correct me if im wrong im just really picky on whats the best for my setup...

And here's a 255 square LS3

Here's a small bore LS7 for the hell of it

I wouldn't say the exhaust side on THESE square port, LS3 or 7 are hurting on the exhaust side at all.

We have a Walmart style return policy. I think it would be pretty crappy to tell a customer who has spent their money with us that we wouldn't take a brand new part back.
Especially if that part no longer will work in his build and we have one that will.
Swiping a customers card, taking their money and then running is pretty low and seems to happen a lot in this industry. We try our hardest to help customers after the sale.
The only thing we don't accept for returns are custom camshafts due to their highly custom nature. I think that's very fair though.
I've been known to still break that rule in select circumstances. Especially if the cam didn't perform the way it should have.

You can use these instructions and put the cam to my attention if you wish.
