I've built some screamin' Pontiac motors, and I've never used anything but massaged factory heads. Are you guys telling me that these Ford heads suck SO BAD that they can't be made to flow decent with some basic port work? I have a couple of local machine shops that do good work for a fair price. I can have these heads reconditioned and ported and still be less than the cost of ONE of those Edelbrock heads.
Like I said, I'm looking to get 325 - 350 Horsepower or so. That's less than one HP per cubic inch. I'm not trying to build a rocket, I'm just trying to make my Galaxie a little less "Grandpa's cruiser" and a little more "muscle car".
I'm gonna start looking for deals on Ebay and swap meets and save up for the big ticket items (headers, new exhaust, etc) and hopefully I'll be able to do some surgery this fall or winter. I've got a monthly budget and I'm not gonna go into debt over this car. I've got some other areas to upgrade too (i.e. swapping out the front drums for disc brakes, new wheels & tires, new vinyl top, etc) so my budget has to cover a lot of stuff.

These are not GM heads. There is more to be gained by porting a typical GM head port than there is in porting a typical Ford head port. The reason is that on most GM heads there are sharp machined edges where the air flow must make a turn that can be blended for increased flow. In most Ford heads the area where the mixture makes the turn is cast in a radius. There is a little gain to be had just below the seat, but not near as much as the typical GM head.
Where the typical Ford ports come up short are the exhuast makes a very tight bend into the manifold. There's not much that can be done about it in the way of custom porting.
The good news with these heads is that they use relatively large, good flowing valves. What you need to avoid though is cutting the seats on the edges of the valves. The 352's and 360's were notorious for requiring valve jobs often. This was because the seat was cut at the very edge of the valve.
