Re: Reputable Cleveland head porting companies.

Putting ANY money into a 302 Cleveland head for a stroker is a COMPLETE waste of money. The head is TOO small to flow enough air. There are inline valve aftermarket Windsor heads that would make more HP as Ross said. A 408 can make 500 hp very easy with a 4V cleveland head or aftermarket inline valve head. Most people that port the Cleveland heads don't do them right anyway.

Agree with everything Mike said. The Ford heads where an option back in the day, BEFORE all the inexpensive aftermarket stuff came out. Mike is spot on about the entire valvetrain needing to be replaced - it's all junk. If you want to keep the cleveland heads, I would strongly recommend that you look at the aftermarket stuff. It might seem like a bunch of money up front, but you'll actually be ahead of the game and end up with a better overall engine.

I agree with all said here, but if really in need of an affordable and good head porter, Les Schmader in Lucinda PA does great work on iron heads and is affordable, especially if he happens to be near you.

However, I agree, a standard zero deck 408 with a set of AFR Windsor heads will be a downright monster and much cheaper in the end. There are even more affordable heads out there, but I have long been an AFR fan for power potential and quality.

351C heads have crappy valves. The heads break off, and they have those multi-groove keepers that hold the valve loosely to promote rotation. These will need replaced. You will need to purchase ALL new hardware. They will also need set up for an adjustable valvetrain/guide plates by a competent machine shop. They will also need rebuilt with new guides, valves job, milled for flatness, etc. By the time you're finished, you'll have more money in them that what you'd pay for an aftermarket set that will bolt to your 351W block, problem free... and that's before you even break open the wallet for a good port job. Been there, done that 20 years ago. I ported a set of 2V Aussie heads for a friend. The valves are TERRIBLY shrouded by the walls of combustion chamber, and need substantially relieved. The bowls in the ports are also a lot bigger than the valve seat, so there's a terrible transition there.

By the time you're finished adapting a set of Aussie 2V 351C heads to your engine, you'll have FAR more money in it, than simply buying a decent set of aftermarket heads that will bolt right on. Once you deal with buying all the hardware, machine work, porting, adapter plates, resulting vacuum leaks, header nightmares, etc... only to run slower than you would with a decent set of aftermarkets, you'll figure it out.

If you insist of forging ahead, just be ready for the reality of it all. This would be a cool combo in the early/mid 1990's, as the aftermarket options were not available. If you press on with this novel combo, I hope you're able to make it work. On the plus side, it won't move a whole lot more air, and won't make a whole lot more power than the stock engine, so that may make the stock fuel injection easier to deal with. That being said, people had fits trying to make Speed Density EFI work back in the day... and that was with simply installing a small cam in a stock engine. People rejoiced when Mass Air EFI came out.

You'll be big dollars ahead, and make a TON more power upgrading the EFI (or switching to a carb), and building a more conventional 408. Of course, it's your build, so you're free to proceed as you wish. Good luck either way... but at least you've been informed of the challenges and realities of it all.
