Sorry for bumping an old thread, but what's easiest way to remedy that?
I had planned on running a 10295, but let a vendor talk me into a 10296 since they didn't have any of the 10295's in stock. I have a stock shortblock heads/cam car, and I think I'm running into this issue whenever I do any spirited driving for more than a few minutes at a time.

Here's a thread about it:

The downside is you need to pull the heads to get to the lifter retainers.

I'm aware and understand that "mod" has been beaten to death, but for a heads/cam street car, is there any benefit? I mean, if the heads are pulled anyways (going from 241's to 243's), while you were there doing lifters and retainers, would it be worthwhile?
This would be with a ported LS6, however....

Say you put in the new pump, with the new heads only to find that doing a spirited highway blast your oil pressure starts to drop. The assumption is that your oil pump is now starving for oil because it's all trapped on the top end of the motor and is having a hard time returning to the pan quick enough. Then you have to pull the heads and modify the retainers to get the oil back to the pan and pickup tube quicker.
I plan to drill my lifter retainers tonight while this is fresh in my mind. I don't road race the car, but I am going to a high flow/pressure pump, so I don't want issues with it later on. There's no real downside to it.

Old thread so i know the search function is working. For those running high volume pumps and worried about oil starvation, use my knowledge to help you.
Fbody oil pan with 8 quarts
windage tray depth into pan, remember the gasket subtracts some
How that equates into the pan.
I run 7 quarts all the time. As you can see, if you factor in filter volume and whats being pumped around inside the engine, you could easily run more.
