Valvetrain(?) noise on first start up

[wishihadas14]

Well, I finally got my car put back together and fired it up today. Sounds nice, I love the deep note of the KA. But there is a rattling noise coming from the engine bay. Sounds like pushrod rod noise knock in a V8. I thought it might just be the valvetrain rattling since there was no oil up in there yet and I did use a good deal of moly putting in the cams. Just had the head rebuilt: completely disassembled, hot tanked and cleaned, 2 new valves, reshimmed for new BC V2's. Car runs great and sounds like a beast, but I wanted to get some insight on this before I disregard it or freak out over it. Thanks.

youre right theres some ticking until oil pressure builds up. if the ticking persists check your guides and or re-shim.
