the head bolts are available from summit. if i remember right they aren't cheap but they are available.
I'd have to agree with you on all points... W style aftermarket heads flow better than ported 4v heads in some cases! As big as the ports are on both Clevelands, they actually flow really sucky due to the shape of the ports. If you have ever seen a cut-away of a Cleveland exhaust port, you would be amazed at how tiny and crowded the port is at it's narrowest point, which is a bottleneck. The ports look big from the exhaust flange, but you can plainly see that only about a half inch back, the floor rises up and blocks more than half that apparent size. 4v heads on anything smaller than 350 ci would have no streetable port velocity due to intake volume. 2v heads have the best ports and valves for a small ci street engine, but the chambers are big and poorly designed to satisfy the EPA. They will cause knock by the very nature of their shape. Aussie heads have a small and effiecient chamber due to the Aussie Cleveland being 302 ci, they have the 2v valves also... so this would be a good option. One thing to note on the Aussie heads is that they do NOT have the same ports as a 2v head. They interchange, but the ports are smaller. If you run any C head, the best thing to do is to port the exhaust completely. Polish the bottom half of the port, but DO NOT enlarge it at all. Do the enlarging to the top half of the port, go as high as you dare. That is where the action is on this head. I ported my 4vs like this. You will definately turn heads when the hood is up. Dave
These are the ones I want. http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=156886&prmenbr=361
Looks like a huge amount of money for heads that aren't as nice as the Kaase offerings, plus you have to finish assembling them and make the streetboss modifications. Advantage: Kaase. Just my opinion by the way.
The Mustang Depot carries clevor stroker kits and manifold adaptor kits. I believe their manifold kit starts at 169.00. Much cheaper than price motorsport (last time I checked).

Sence we are dreaming here how about these heads........they also make them for clevelands too http://www.araoengineering.com/Ford/frdsmb.htm
Thomas- Ooooooo! Those are neat! No money here. especially now. Look for the reason in the off topic section sometime in the next few days...
Brainstorm... Someone should make aluminum Cleveland heads with the following mods: Raised exhaust ports using the 4v bolt pattern. This would cure the port problem and make headers easier with the larger port face. Quench chambers of course... maybe even hybrid quench chambers with swirl properties. And the clencher! They should offer them with W style intake ports/bolts. Then you could make any deck height 'Clevor' and just bolt on any off the shelf intake available for that deck height block! 2v ports are very close to W ports, I saw one Pantera site where a member modded a W EFI intake to bolt to his 2v C heads... the problem was not the ports, they lined up perfect, it is the intake bolts that are straight on the W and angled on the C that make the problem. Think of it... An aftermarket aluminum, high volume, canted, decent valve size, good chamber head that with some thought could easily surpass the efficency of an inline head like the W. One that would bolt up with off the shelf pistons, pushrods, SBF intake, and Cleveland header flanges. The swap would be easier and better than ever. Dave Edit: I would also like to mention the benefit of the C head exhaust face... The ports point down to the ground, instead of out to the shock towers. This is something I thought was awesome for fitment issues and allowed big tube headers when I did my 351C swap. If it wasn't for the spark plugs being on the side of the head, shaving the towers would not even cross my mind. And we all know how hard it is to get big tube headers on a W head. The C and B302 headers for a Maverick START at 1.875" primaries and go UP from there! A note on the Araq heads, years ago they prototyped a rotary valve head for the SBF. It was the $**t! No moving parts for the entire valve train except for the rotary valves! They were metal spheres that blocked the port when the valves would be closed, but then they had a port run through the middle that would flow as the rest of the port when the valves would be open. They had no harmonics or RPM limit. No drag from moving parts or parasitic HP loss. Nothing to break, less weight. No cam. I wonder where those heads are today...
Now the next question. Do any of you live close to SE Okla. and have a set of good rebuildable m or c heads for sale??
http://www.chiheads.com/main.html Australian designed cleveland heads. All the good stuff you just talked about. Also for the uninformed. Edelbrock is releasing a set of 2v cleveland heads and RPM Air-gap manifold due out in 2-3 months!!!! The era of the Cleveland and Clevors HAS COME AGAIN!!!! http://www.pim.net/newprod601.htm
Seems like every time someone comes up with a really incredible design like that, it dissapears. hmmm...
