The typical Indy spray bar valve cover has the tube located right up against the inboard side of the V/C, and they spray straight down onto the rockers, so you can still put the vac pump fitting pretty much anywhere you like.
If you can get lifters that won't allow the top end to be over oiled, then my preference would be to pushrod oil. This assumes you'll be running rockers that are pushrod oiling compatible.
That being said, I have several customers running Jesel rockers with the spray bar oiling, and none of them has ever had any issues with that system.

I have run spray Bar Oiling on both of my big motors. Both with .800" cams. Never any problems with wear and both are street cars. I think that setup helps cool the valve springs, which is good on a street car.....

My next bracket motor, 400 block, 4.300 stroke, Indy CNC ported 440-1 heads with Jesel paired rockers has both pushrod oiling and spray bars,no restrictors except what is in the covers with the fittings they come with. These Jesel rocker arms come with hollow adjusters with no provisions for pressure oiling the shafts, roller tips or any thing else I called Jesel about this and they insist that splash oiling from the pushrods is more then enough to oil this system I haven't ran this motor yet, I'll post more about it after I put it on the dyno or in the car

I use Iskys bushed E-Z roll max lifters. They are the only lifters that have ever lasted on the street for me. Needle bearing lifters always failed on me. Springs are PAC 1224. 275# @ 2" approx 850#@ full lift. I change them out every couple years......
