You're probably ok at idle, does it rise when you rev it? Like stated some people block the DOD towers when they do the delete, others just use a gen 4 valley cover and call it good. I did on the one I did and had no problems. Since you're 2x4 it's easy enough to slap a fresh o ring in the pump and check for blockage in your pick up. When you did the cam did you replace the cam retainer or re-use it. I've seen people have oil leak past the plate when re-used but usually it's a good leak and you have no oil pressure. Also, are you using a stock gauge or analog? If it hasn't been done it's a good idea to replace the OPS and the screen under it with new GM parts.
