I think what he meant was that the pictured head (Tunnel Port) was the original intended head for the Boss 302 Mustang, not that it IS a Boss 302 head. How would that feat of magic be performed?
You guys are treating this like it is some kind of big deal. I was talking about putting Boss 302 heads on a 302 - the two barrel manifold will fit fine in that case. If you try to put Boss 302 heads on a cleveland you can't do it without a special manifold and changing the water flow through the cleveland heads. On a 351 Windsor you would have to use a special manifold to match the ports but that wouldn't make any difference on a 302 - It would bolt on. The exhaust pattern for the Boss 302 head is the sam as the pther "windsor" engines. That is another way to tell the difference between Boss heads and Cleveland heads. You guys have to stop calling the Cleveland heads "Boss 302" heads - the Boss heads used guide plates and screw in studs - the Cleveland heads use bolts through a square mount pedistal into a slot in the head where the bolt anchored the pedistal to the head. They don't need guide plates but the Boss 302 heads do because they use studs. That Tunnel port head was never intended for street use - it was engineered for CanAm racing and it was a flop! You guys can go ahead and call your Cleveland heads Boss heads if you like but if you ever try to sell one to somebody looking for a Boss 302 head you are going to have a fight on your hands.
OK, Just as everyone here says "this thread is usless without pics" Here ya go. The boss 302 head will fit a 351C with the water passage mods and a "STOCK" 351C 4V intake manifold. The Boss heads will fit a 302/351W with a special intake and or stock manifold with special spacers. None of the parts are an exact bolt on the the other engine without mods. Case in point-----Here are some pictures to prove it.
I MAY STAND ALONE ON THIS, BUT DOES ANYONE ELSE THINK THIS INFO IS A LIL OFF/POSSIBLY WRONG? I HAVE NEVER EVEN HEARD OF A BOSS 302 HEAD OR CLEVELAND HEAD HAVING ANY PORT THE SAME SIZE AS A WINDSOR HEAD. FROM WHAT I HAVE READ OVER THE YEARS, THE BOSS 302 HEAD WAS BASED ON THE '71 4V CLEVELAND HEAD.....JUST MY THOUGHTS
Boss/Cleveland Totally agree - This info is WHACK !!!! Twilight Zone stuff - CAUTION - Do not try any of this at home - or anywhere else for that matter.
I thought Chevrolet made the boss 302 patterned after thier big blocks using a 307 block and a 283 crank? Why would you want a Chevy engine in your ford?
Really? Could have sworn my Boss 302 heads had the same exhaust ports and bolt pattern as the 351-C four barrel heads. Actually......THEY DO. Welcome to the worldwidewebofmisinformation.
Oh, I'm sorry. That's an incorrect answer but thanks for playing our game today. You don't need a special manifold. You have to plug the water outlet on the intake manifold face, drill the water transfer holes in the deck face of the heads, and you can use any 351-C intake manifold designed for 351-C 4V heads. Yes....due to the taller 9.5" deck height of the Windsor block. Actually.....the Boss 351 Cleveland heads used studs and guideplates too. Standard 4V and 2V Cleveland heads used the "slotted pedestal" mounts. Certainly hope this clears up any confusion. You're "almost" right about the Boss 302 stuff, Paul. Almost just doesn't count sometimes. And before you ask.....yes, I've done plenty of Boss 302 and 351 Cleveland engines. Built the first one when I was 11 years old. Don't ask how many I've built either. I quit counting at 40.
LOL, it is getting weirder and weirder. BTW, even if the exhaust manifold bolt holes were the same on the Boss 302 head vs. std. Windsor, the port mismatch would create serious reversion problems. The Boss and cleveland heads have a diagonal exhaust bolt pattern, the windsors have a horizontal one. They are not even close.
Paul, Like Dave (Ratio411) said," I give up!" You have been as least partially wrong on nearly every one of your posts on this thread. If you read through all the posts, you will see that no one agrees with you. No harm done as long as nobody invests any time or money based on what you have posted. To anyone who needs correct info, please go the Boss 302 site and verify what you need to know from people who know what they are talking about, rather than trying to decide who is right & who is wrong on this "Twilight Zone" thread.
