Make sure you get the FelPro gaskets with rubber inserts, most parts stores are familiar with 'em. Plan on an oil change, I usually wash the lifter valley down with solvent and change oil right after I finish the job.
I wouldn't wait, if a decent amount of coolant gets into the oil it'll take out rod bearings. Seen it many times.

Thanks
My mechanic says they send the manifold to be machined to ensure a flat surface. Is that needed?
