Mopar [HEAD] Aches PLZ HELP!?

So are bigger valves better,
Build dependent, in a 318, more likely not in your case. The dyno may say one thing, the feel of the ride is another.
if the chambers r still smaller?
Chamber size being smaller (If such is the case) will keep the comp. ratio up and not give away any power. You'll need approx. 1 full point or better to equal a iron head.
Would putting 2.02/1.60 valves in a 302 318 head be a good Idea?
No
Keep in mind the pistons are .030 which should raise the compression a bit with 318 heads.
going .030 even with a stock replacement piston will raise the ratio. Actual part number to the piston would help. Otherwise, I'm left to fly blind and assume. I have assume.
The pistons are 10.5:1,
well, that helped, but only a little. The pistons can be rated @ 10.5-1. But the actual ratio is dependent on the rest of the areas. Like head cc amount, gasket thickness, gasket bore, where the piston actually sits, domed piston, how many cc's, valve relief cc's. piston above deck amount. It is just not that simple to say I have 10.5-1 pistons. are bigger valves better?
tsk tsk, repeating questions get answer exactly the same way as the first one did. Or, (he he he) See above. ;)

The Mopar engines book has ways to calculate actual ratio. Piston calcs on line are only as good as the info entered.
