Holley rebuild questions

[HSSS427]

I'm in the midst of rebuilding my Holley 4150-9379 - 750 cfm, no choke, mechanical secondaries, double pumper w. dual 30cc accel pumps, 68 jets on primary, 81 on secondaries. Primary accelerator shooter was a 28, secondary was a 31.

Engine is a '65 block 427 side oiler w Shelby aluminum heads, Isky cam 250 duration, .525 lift, '66 aluminum medium riser police interceptor intake. Running 9.5:1 compression.

So far I have:
1. Disassembled and cleaned everything
2. Replaced main body w. ProForm main body
3. Replaced throttle plate with ProForm plate - the original plate had an older style secondary linkage that used a shaft cast on the old main body so had to get a set up with the newer secondary linkage - plus the new one is purple and looks cool
4. Went down a size in jets: 67 primaries, 80 on secondaries
5. Installed a 50cc accelerator pump on the secondaries. Kept the pink cams on the primaries, and have the brown ones on the secondaries
6. Right now have the accelerator shooters that the Proform came with, but they don't have any numbers stamped on them so don't know the sizes - was going to change primaries to 35 and secondaries to 37s
7. Installed the blue removable gaskets
8. Installed new nitrophyl floats
9. Installing a 1/2' phenolic spacer so the 50cc accelerator pump will clear - it's tight now between the scoop and air cleaner - a 1" spacer was too high.

So, here go the questions:
1. If the 2 trains are approaching when will they pass? OOPS, bad flashback to word problems.......

1. Anything glaring with the above set-up as a starting point? Haven't run the car yet so don't even know what response I'll get.
2. Should I trim the gaskets to the size of the holes they match up to? ie the transfer slot holes are bigger than the holes in the gasket - should I ream out the gasket? Same for other areas?
3. I have the 6.5 power valves in. Am I going to need to get lower ones?
4. I'm assuming I put gaskets between every "layer" of the stack, with no sealer or anything on them. I've got a turkey pan, so I go gasket between intake and pan, gasket between pan and spacer, gasket between spacer and throttle plate.
5. Any problems using the original metering blocks, fuel bowls, inlet needles (replaced w. new but same as original) with the new main body and throttle plate?
6. Any other stuff I've overlooked or would be a good tip to take care of before I put it all back together and start up?

I'm now in for about $300 - probably should have just gotten a new Barry Grant, but it's been fun to learn. Like disecting frogs for the first time

Thanks for bearing with the long winded message......
