I think so, do the pro comp heads take a special head bolt or just the std set. Most heads that are diff just have four longer bolts above the exaust ports that can be bought separately.
I am not in any particular hurry. Just in the parts gathering phase for an engine build. Still not sure if this engine is going in an old pickup or a boat, so it may even require another trip to the machine shop for appropriate clearances, depending on use. So, whenever you are in a position to ship them, let me know and I will pay you however you want to get paid!
