I'm unsure of some of this information, so take it with a grain of salt.
I don't think any of the valvetrain parts are interchangeable. hondaautomotiveparts.com lists different inventory numbers for 1995 Accord VTEC's and 1995 Prelude VTEC's for valves, retainers, and lost motion assemblies. I assume they're different for everything else in the valvetrain as well.
While the blocks are not identical, they are similar. The bore and stroke numbers for F22's and H22's should be the same. Clutch and tranny parts are interchangeable.
As far as Gude goes...I (and most others here) would caution you to stay away from them. They're not quality parts, and they use reground camshafts (bad idea). Try Crower or Crane if you're looking for a cam for your Accord engine. VTEC or non-VTEC?
