Help spec'ing out a new small block
The valves fit without issue…this is on my dead mock up block with 4.03. New one is 4.09, so there’ll be just a little more room (030 on the edge ain’t much though). Sorry, best pic I could get at the moment:
Whether or not you think you want to notch for shrouding is up to you, but Valley didn’t on their EM motor and it did pretty well.
