Normal wait time, after a lower manifold?

Opps, I kinda miss read the question. Yeah, you can start up the car and fill the anit-freeze right after you get all the other stuff on. Just don't take it out for a good thrashing. I got greedy, took it up past 5k and pop...

I would let it set. I went out and tromped on mine about 2 hours after the lower had been torqued down and I blew the seals out on the front and back. I would let it sit overnight just so you don't have to do it over again.

That would suck! In a perfect world, the lifter valley is not supposed to become pressured during normal operation of the engine...

After you get everything put on, you should start your car and let it just idle for a while to let those gaskets set, after the car heated up and ran for a while, take it out and baby it for a while, but after a couple days of breaking it in, time to get on

I'd let it sit for 3 or 4 hours so that the RTV can properly cure. Otherwise, you may get a leak!!
