Try thread sealant on block drains, check the intake gasket at the rear, check the weep hole on the circulation pumps. Buy a bore scope camera from Harbor Freight to inspect areas you can't see easily.

Check you exhaust hoses and clamps. Sometime they will leak at higher pressure/RPM's. Seen it more than one. Had the same symptoms on my own boat, chased that water in the bilge issue. Took a mirror and went around all the exhaust hoses and clamps. One was not even all the way around. loosened it up and moved it even, water leak gone. Rechecked a couple of weeks later and it was about 1 turn loose. .
Id go through an wiggle/check every hose connection. Likely a similar issue, especially if warm water.

If you are asking about the ones in the exhaust manifolds I just changed the exhaust system last year to stainless marine thinking the stock cast iron manifolds had a crack in them but I still have the same amount of water coming in. Is there other drains I am not seeing?

As others have mentioned, look at the block. High water pressure on a 502 can cause the head gaskets to leak to the of the block. My 502s also pegged the water pressure meter at higher rpm and speed.
Hoping it's just a hose leaking. Let us know what you find.
