need some help with selecting cylinder head Mopar 408

Not sure the pin height on that piston, but if it's close to zero deck, you're gonna have to watch where your compression ends up with aftermarket heads. What type of fuel do you use? I'm not familiar with the quality of pump gas in your area. The cam selection can bleed of some compression if need be.

the pump gas i use is 98 octane
the cam is a P4120230 but when you order it the number is P4120231

(moper)
so i maybe need to change the pistons? :(
I have a pretty tight budget for the heads 2325 $ is the max i can afford right now.
