When combustion chamber size increases, compression drops. Ford high performance 289 and 302 engine heads all have cast in valve guides that were machined and were never fitted with the heavier rail rockers.
Ford, as well as all of the us. C7ze a hippo valves Eventually, they work their way into the retainer, which can fail, drop the valve, and destroy the source diffed. 5cc outside of the five to six bolt bell housing pattern change for 1965, the next most significant change for the small block Ford is valve train and valve covers in non performance heads the cast in guides were eliminated necessitating the use of rail rockers but saving Ford a lot of machining and therefore money but also reducing rpm as the rail rockers are heavier and sloppy at high rpm due to the lack of the precision valve guides.
45 inch valves on a later 302 engines will raise the compression. Instead of a push rod guide hole cast into the cylinder head, the rail rocker arm sat on a taller valve stem, which kept the rocker centered on the valve. Port and valve sizes remain virtually the same for heads through the years, but combustion chamber changes a lot after 1971, chamber size volumes got larger.
At first thought, this is a good idea. If you want to go to screw in studs, you can remove the pressed in studs by putting a socket on top of the bare stud a washer than a hardened nut. Combustion chamber size isn any different from the 2v and 4v head either.
Automakers, dropped compression to both improve emissions and deal with steadily falling octane ratings due to the elimination of lead, but with a corresponding drop in horse power. Contrary to all you ve heard through the years from you buddies, the 289 high performance cylinder head does not have larger valves and ports. Push in studs was just a matter of machining the casting.
5 cc chambers with Use of the push rod guides meant they could use ordinary non hardened push rods. But, when you consider engine wear and the possibility of using a high performance camshaft, this idea is a bad one.
If you are going to use a high lift cam you do not want rail rockers. When it comes to the 289 and 302 Ci engines, port sizes never changed, nor did valve size except for the boss 302 which used 351 Cleveland canted valve heads. You then put ice on the head and tighten the nut which will pull out the pressed in stud. As the valve stem tip wears, the side rails get closer and closer to the retainer.
