they used the colors to identify their engines. for example the flathead six cyl.from the 40's was called the green diamond. i believe the pickups in the 50's had the black diamond. the big trucks had the red diamond. not sure which engine would have the same head as the 263 engine in the 560. guessing maybe the black diamond but its an older model.

The engines closest to the 263 in the IH truck line are the Silver Diamond ['50 to around '55 or so], Black Diamond [but only the 220, 240, and 264...the BD 282 and BD 308 are closer in design to the old Blue Diamond line of engines], and the BG 221, 241, and 265 engines used up through '68.

The Silver Diamond engines are all "straight-valve" engines, and use a narrower valve cover than the "tilt-valve" engines. Black Diamond engines could be either straight-valve OR tilt-valve engines. A straight-valve head seemed more prone to dropping exhaust valves than the tilt-valve engines, but that's only what I've been told. And a straight-valve head on an engine with tilt-valve pistons will yield around 12.5 or 13 to 1 compression with no other changes, according to the experiences in mix-and-match of one member of the OldIHC.org discussion boards.

But how that compares to what effect you get when swapping one of the truck heads onto the ag block, I really can't say, as I never got the chance to try it.

watch piston to cyl head clearence issues on the 301 piston, but would have best chance of good clearence with the 301 firecrater,, the smaller bore engines like the 263, can have too tall of dome and will hit. port match the exhaust with the gasket, along with the exhaust manifold. itll jump a 301 cyl pressure up to 250 pretty easy. good 20hp easy. it is like the lp head for the 450s. lol... 67717 possible part number..... got old pics but have to really dig. lol
