Zong 250 Spark plug

Question, my Zong 250 (223cc) is basically a clone of the Honda 230. Now Honda recommends the NGK DPR8Z spark plug which is the same as a DR8EA except it's longer than the DR8EA & D8EA.

Thoughts on which should be used? The Honda 230 is reported to have head issues if a DR8EZ or D8EA is used instead of the proper length plug. Also, if the bike has a resister cap installed I should be using the D8EA correct and not a resister plug like the DR8EA

And to confirm - Correct spark plug gap is......

D8EA is correct for CB and CG
Check common china engines like the hawk 250 for plug gap
I think 0.8mm but do a quick search
