ooooooooh... Like a boss 302 head as compared to a 289 head then

boss 302 head is a cleveland head

a Boss302 is a Windsor head, there are differences

The Boss 302 head is a 351 Cleveland head that was modified by ford to run on a 302 block . All though the Boss 302 engine was released first these heads were intended to be 351 Cleveland heads . This came about because the 302 tunnel port trans/am engine was a expensive flop. Ford needed an engine to compete with the Z28 camaro for the 1969 race season .

thats a 2v port , George Strigle at Clay Smith cams told me once that he had a customer that had a 4v head on a sand rail , always running at the back mof the pack. he suggested to his customer to install a nicely ported 2v head on his motor, amazing thing happend...nobody in his class could beat him afterwards. A good ported 2v head can flow 260-270 cfm.

thats a cleveland head. 2v.

A well ported set of 351 4V heads can see a flow number close to 400CFM . I have been racing Cleveland's since 1970 , I have never seen 2v Cleveland in my class that was faster than MY 4v engines .

The Boss 302 head was produced before the Cleveland was so the Cleveland head is a Boss head modified to make it unusable on any other small block Ford - only it can be modified and the after-market guys made some manifolds for the swap.

The Boss head was released before the Cleveland but, the Cleveland was in development for over a year , ford realised that when the tunnel port was reved to the point were it devepoped its power it would not live . ford lost the chanpionship in 68 .They needed Better ahead for there engine and the Cleveland head was the easiest and cheapest way to go . I am pretty sure it was Bud Moore that decided to try the Cleveland head on the tunnel port block . Ford had been working on the Cleveland head before the Windsor was put into cars but it had some flaws that had to be worked out . Ford had BS'ed there way through the 68 season with out having a production tunnel port and the trans /am sanctioning body demanded 500 cars built for the 1969 race season , or the mustangs would have to revert back to the old 289 . That is why the 302 boss engine was installed in cars before the Cleveland was realeased.

I agree on the 2bbl cleveland head ID. Here is a pic I took some time back. I like the answer you gave about the reason the boss 302 heads are so much like the clevelands.
