Milodon 31186. 8 quart stepped pan with dipstick provision. For Mk 5 and 6 big blocks.
I am using the Mk IV version on my 496 big block and have no clearance issues at all with stock power steering. I actually run 6 quarts in the pan and have had no issues at all.

You'll have to run an electric fuel pump, production (non-crate) Gen 6's don't have a fuel pump boss. You can remove your cam and send it for a regrind, Delta in Washington State is who I use. Sell the heads and find a set of semi-closed chamber heads (215, 290 and 063 castings) to bump compression close to 9:1. You can use adapters to allow use of early 90's smallblock serpentine systems. If you're not going to use an oil cooler, email me at 81vette4speed@suddenlink.net, I'll send a GM bulletin that addresses a series of 90* turns that'll cost you a bit of oil pressure and shows how to correct it.
With priority mains, 4-bolt main caps and ability to run OEM hydraulic rollers, the Gen 6 is a favorite of mine. I think I'm down to 6 or 7 in the shop, gotta start looking for more...

I've got two 427 tall decks, one 30's over 454, a bare block 454, a 396 and a 60's over 350 (how the hell that got in there I'll never know). So yes, I need to start finding some more also.

The Moroso 20411 fits nicely in the Corvette C3.
I have this in my 1972 with Gen-V 454.

You also may want the pickup for the oil pump:

And the dipstick kit:

I don't find the Moroso pan to be to low.
Have a look in my "garage" and you will find a couple of pictures where you can see the bottom of the pan.

When it comest to hedders you can use the same as fits in Vette for the older Mark-IV engines.
But if you chose to go with aftermarket aluminium heads be aware that the exhaust ports are raised on most after market heads witch may/will cause a problem with hedders to frame clearance.
I run the Hooker Supercomp 2-1/8 fullength wich fitted nicely when i had my cast iron heds but when i installed my new AFR heads the needed some massaging.
The AFR 315 heads has less raised exhaust ports than for example Brodix and other race heads.
The hooker Supercomps long 3,5" collector is the first thing to hit the ground when going over sidewalks or speed bumps.
If you planning on running a manual gearbox the Gen-V And Gen-VI engines don't have the threaded hole in the block for the ball to the Vettes original clutch linkage but Scoggin Dickey has a bracket that solves this problem and it works fine, I have been using that one for 5 yers now.
