1st 318 rebuild

I am aiming at reasonably stockish but not quite .also got with the blocks and heads an eagle cam #he1423al then a #12 on its own.Havnt been able to find any info on this yet. Have pistons for 360 but havnt gone right thru them yet to check condition.Probably depends on how easy it is to get a crank.
Cj limo is an Austrlian made Chrysler by Chrysler.
Should be a pic
Other option could be 318 with 340 heads? as have 2 complete 318s sb.will they still affect comp like 360 heads??
(PS pic is not my car just got of google.)
