Question 350 build advice

Im starting with a bone stock 350 carb engine. 4 bolt main out of a k20. It runs good now but im no fan of stock crap. I have built a few engines but i know i dont know it all so im asking what yall think.

I have a good set of .030 over aluminum pop ups that are 11:1 comp ratio with factory heads (I fogot the chamber size). I was going to keep the stock bottom end as it is fine but add a high volume oil pump and some ARP rod bolts. Also static balance the rods/pistons.

As far as the top end goes i have a rebuilt set of stock vortec heads with the 1.94 valves and they have not been machined for a bigger lift cam. I also have a set of cammel hump 1.94's with 3/8 studs and manley push rod guides. My only prob with these is the damn bolt holes being missing.

I was planning on running a dual plane air gap edelbrock with that center divider that is cut down a bit for more power on the bottom end but retaining the high end power band.

Cam is undecided. People supposedly love those vortec cams because they are factory rollers and make power at like 2400 rpm.

This truck will be geared decent, 4.56's with a th400/208 and 42's for tires.

The truck will either be on race fuel to deal with the high comp or on propane, undecided on that at the moment but if i build the bottom end for high compression then i can run pane and be fine. Anyhow let me know if im just going to end up with some turd or not.

IMO, first unless your upgrading the amount of oil in the pan, like with a deep sump or kick out, then I would stay away from the high volume oil pump. Stock pressure melling fine for 6500 rpm with some smoothing/opening on the return holes in block and debur and smooth edges in rear main where the oil flows from pump.
The heads you have are great with certain builds but IMO I would get a set of 441 or 882 stock 350 heads for this build. Mildly port them with 2.02 1.60 valves and machine for screw in studs/guide plates. The reason is the piston dome shape may be wrong for your vortec heads combustion chamber and you will have machine work to do still to allow for higher lift cam. The old double humps are decent but no bolt holes and usually are ragged in most cases + crack prone.
If you could drop the $$ all at once these (or simular) would be about the same cost with greater reliability Summit Racing SUM-152123 - Summit Racing® Cast Iron Cylinder Heads for Small Chevy - Overview - SummitRacing.com
My cam for this would be
Lunati 10120701LK - Lunati Voodoo Cam and Lifter Kits - Overview - SummitRacing.com
Make sure you learn about the correct oil to use and break in properly.
This would have some nasty snappy torque with your combo, I think you would love it. It would not be a turd.... IMO
