340 Build help please.

Mine's probably right around there the heads have oversized valves, but they're hogged out. It's a virgin bore but they're 10 and a half to one Pistons. I used the 484 purple shaft cam, a holley strip Dom, (its ported and matched to heads)and a 750 vac, patriot headers, good Springs, locks, and retainers on the valves and head, a large capacity pan and HV oil pump, feeding fully grooved Mains, Here's the Clincher the heads I'd had laying around for a long time when I bought the rest of them parts it was around 2010 things have gone up so much by now it's crazy.... maybe you can find some stuff at a swap meet or something
