Looking for some input on 360 LA build

Hello guys, I'm finally back after a few months since getting my junk mabbco engine. However the $2,000 paperweight is finally going to make some progress. I have recently tore down the engine completely and had a local machine shop check the block to make sure it was all good. Only cost me a couple hundred. However moving onto the build of it I'm looking for some input on some components, so here's what I got so far.

block- 1991/1992 LA roller block

crank- Stock 360 la crank

Carb- Edelbrock avs2 650 cfm 4bbl (edl-1905)

Intake- Weiand action plus (8007wnd)

Camshaft- Howards cams 711915-12

Pistons-Keith black 107 4.040 (UEM-KB107-040)

Lifters- Elgin HL-2269s with stock dog bones and spider

Pushrods- stock pushrods

Rocker arms/rocker shaft- stock rocker arms and shaft

Timing set- comp cams 2103

Headers- hedman 79080 long tubes

This is everything i have so far for this engine now here comes my questions

What heads should I use? I see trickflow, speed pro , and edelbrock all have some nice looking heads looking to stay under the $1,600 range on some nice aluminum heads.

Also will I encounter any piston to valve issues, I have yet to measure deck height with the rods and pistons in the block but based off the cam size and rocker ratio and stock pushrods I was wondering if it would even be an issue.

I'm also torn on my connecting rods if I should get a set of scat I-beam rods or a set of speedmaster H-beam connecting rods, either way I am going to have to get the crank re-balanced as I changed my piston and rod setup.

And finally the long drawn out controversy on the oil pumps, should i go with mellings high volume or standard volume i don't know if it makes a difference just looking for someone's 2 cents.
