Fitting a 1968 302 4v heads on a 1993 5.0 roller motor

Do you use the '93 push rods and rockers for the application of the '68 heads?

68 heads are stud mount, so no on the rockers and as far as push rods go, you should be measuring for such

If you must use those heads, get an adjustable pushrod and measure with it for the correct length.
Remove a valve spring and use a light spring with the adjustable pushrod as even a stock valvespring will be too much for the pushrod, it'll break it.
If you are going to use those heads (why?) you'll need to get a set of valvesprings for the cam, they are somewhat differant than the '68 springs........
