I don't participate in Chevy vs Ford wars, but the have been plenty of ford championship trophy's in racing.
I'll call your statement rumor and innuendo, but I do invite you to study the flow rate of the original boss 302 heads. I won't even mention the Ford gt-40. Oh wait... I just did.
Point being, American muscle is American muscle- Chevy vs Ford vs dodge is just pointless to me.
At the end of the day though, all 4 of my vehicles are Fords.
I should have known a Ford guy would jump on this but.....
The 302 Boss is generally not considered a small block Ford typical head....rare to start with, Canted valve, not the typical tiny valve inline head as used on all other Windsor based engines.
And you can't just directly swap them onto any stock 302 or 351 W short block without making a bunch of other changes.
The GT-40 head really ain't all that good either....it barely flows what a stock Smog era SBC head flows.
Just look at the flow numbers of any inline valve Windsor head.
Don't get me wrong, I love the Cleveland head, it is a monster, especially on 393" and bigger builds.
A 400+ cubic inch Clevor in a early Maverick would be one of my dream Ford builds
Seems like Ford was always like this since the muscle era....the heads were either all conquering...or nothing.
Only the Boss and CJ/CobraJet stuff got good heads, everything else got nothing.
Even the 289 Hi-PO got crummy heads.
