Stock 360. Add Cam and intake.

As of late I have decided to overhaul this engine with mild performance with a econo budget and some tlc. Considering that I need an engine for 2 years or so that is fun to run and reliable, I am changing gears a bit.

I have a new RPM (not air gap). I have new dougs full length. I have a new MP dist and probably will run GM HEI or FBO ECU. Carb will be a rebuilt large or regular TQ with square to spread adapter, possibly switching to a QF later if needed. Running 3.55 SG and 727 with stock converter in a stiff suspension duster factory no ac manual steering.

I plan to have the block dipped and all oil galleys cleaned, checked for cracks or issues. New cam bearings and freez plugs. I guess typical machine shop cleaning process.
I am prob going to mill / square the deck too.
I am hoping the cylinders and pistons are good enuff to run stock bore / factory pistons. Having the bores honed.

If bore / pistons cannot be stock, I will get KBs and recondition the rods.

What suggestions would you all have for stock J heads, stock pistons?

Should I mill the heads allot? I plan to surface heads, install 2.02 valves, have the ports cleaned up and 5 angle valve job only. I reckon that would be a good bet on the heads. What is a common price for the above head work?

So, what basic stuff would you do to the heads and block?
