Looking to buy a set of aluminum heads for my 350 Mag. Will be adding a cam also. What heads make the most power at a reasonable price?

What exhaust do you have?

I will be going with EMI Thunder

Hard to beat the Vortecs by much when under 400hp.

Oh, cost vs power aluminum head and made in the usa, Profiler 180's and then probably Brodix IK180's.

Here's profiler : http://www.profilerperformance.com/r.../sbc-23-degree

You will have to change back to a non Vortec intake though, on both, so add that into the cost.

Those profiler heads look like the best bang for the buck american made budget SBC head out there. I would love to hear from somebody who has some real world experience with them. The 355 in my Vette is just screaming for some better heads.

AFR 195 is likely a strong performer. Dart would be a solid choice too.

Real experience.
Stock (original to boat) Merc '91 260hp mag short block. Schitload of hours.
Brodix IK 180's
Weiand Air Strike
BG 650 vac secondary
Stock tbolt ign with MSD HVC canister coil.
Comp HR 218/224 / GMPP HR lifters
Scorpion 1.6 rockers
Eddie MArine exhaust

20ft boat . Gained 15mph all said and done. 53 and change to 68 and change.

Now over 70 with same motor...but that's another topic.

I've been reading on it some and it seems like most people end up going with 170-195 cc intake runners. What are the advantages/disadvantages of going bigger or smaller?
