360 build

Well I broke down and ordered a Weiand Action Pluse intake from summit and it will be here tomorow. I figured that the old offy 360 intake is old crusty and has 3 helicoils in it already so to hell with it.
I have a new eddy 600 carb that was only 4 months old when the old 360 died.

Rocker arm shafts are bolth in the right positions, all the oil passage plugs are in place, everything is torqued to the right specs.

Prelube... I have a priming shaft, once I prelube it and install the intermediate shaft gear what if it ends up being 1 tooth off and I have to take it out to line it up so the rotor faces #1? With the pan and intake on it seems like it would be next to impossable to take it back out. The smallblock mopar book says to install the intake before prelube.

Break in... 2200 rpm for 30 mins??? (told that by 3 differant people so far)

Change oil and filter after break in and test drive?

What oil is best for a new motor?

Is there a filter that has a valve in it so when I take it off I wont get oil all over my exhaust pipe? I have a right angle adaptor for the oil filter but I dont have enough room for it, the exhaust tube passes right next to the filter and into the sidepipes. I have about 3 inches to play with so I have been useing a short Wix filter.

Thanks for all your help guys, Im getting all antsy and every time I walk by the motor in the garage Im looking at everything and thinking about what you guys have mentioned and double checking everything.
Im use to bolting things on, cutting, welding and fab work so this whole new spiffy motor thing is new to me, YOU GUYS ARE A BIG HELP!!!!!
