You can also use ARP 7/16" rocker arm studs. That's what I am using with my 7/16" NSA Pro Mags.
Don't get a high pressure pump. Just get a GM replacement standard volume/standard pressure oil pump and install the GM white spring.
I wouldn't recommend replacing rod bolts without reconditioning the rods and installing new bearings.
I spin my stock bottom end to ~6300-6500 rpm regularly without issue (your results may vary, lol). Which is fine to get the most out of the CC503.

Why not go for a high pressure? Care to share a technical explanation?
Some say its safe, and the car's manual says its good if your not in the red.
This is of course, considering the gauge is reading correctly, or the sending unit is not gone haywire.

My gauge is already reading at the middle at idle when cold, at the 1st quarter when the engine is hot, and when driving right at the middle, a bit over if I have my foot down. Could be the oil the garage put in when I gave it in for an oil change (I had to because I didn't even have time to wash my car, otherwise I do all the work myself). I got some 10w30 Ford Sythetic blend oil and will try it out before I go for changing the pump.

I meant no on a high volume pump. Then you run the risk of pumping the pan dry, so I've heard. If you have a std volume/high pressure pump, I think you'll be fine. FYI, I have 60psi of oil pressure upon start up, 30psi hot idle and over 60psi WOT. Stock bottom end. Bearing clearances also dictate oil pressure. The newer engine has much stronger oil pressure than my old one. I used to have ~20psi hot idle, which is much higher than the GM spec of 7psi min hot idle.
I thought I might as well swap it while the pan is out, whether the pressure sender and gauge are reading accurately or not. And its not expensive either.
I am reading a lot of bad things regarding knock over at the LT1LS1 forums due to full roller rockers, are they really that noise to cause false knock?

I thought you might have gotten confused. I did say high pressure pump as in standard volume, sorry for not mentioning the standard volume part.

On stock lifters, how much pre-load did you set?
I will also try to adjust them with the engine idling, make sure I get as close to 0 as possible.

I am hoping to data log my PCM and send Solomon the file to sort it out for me. Just trying to finalize my parts list to see if I can spare for the cable yet, or not.

I doubt they would do the exchange program for overseas anyway.
I will give them a shout and see what they say.

Unless I can send him a log to start with and send me the tweaked file to upload.
