1st 318 rebuild

To use 340/360 heads on a 318 you need KB pistons zero decked, cylinder head chambers blue printed to 68cc and a 0.040" gasket for 9.1:1CR
hEY 273:
In order to zero deck the pistons do you have to assemble the block with crank and pistons to get measurement or is there a formula you can use to figure out how much to remove?. i read some where you can fill the conbustion chamber of head with a seringe to get the cc volume which makes sense.
The block is 001 over tolerance from stock on 4 cylinders so do i just go 010 over or go to 030 over as it seems like the standard and parts are readily available. Also Is it better to use 360 rods with pressed pins that are a heavier rod or go with the lighter 318 floating pin rods??
Car is just going to be weekender trips and such and likely never see a track. Hp is not crtical just plucked some numbers outa me head but want bit more than stock.300 got nice ring to it.:D
have 360 dual plane inlet man and exh and stock rebuilt 2brl carb(so i was told)
can always replace with holley later.
Do some mild porting on heads just to remove lumps bumps and casting marks etc.
Any help /advice greatly appreciated.:newb:
