i have both of these and i am gonna put it together but will this combo give alright results or would a 1.5L block be better ?

 

Its only up to you if its worth it or not, not other people.

90% of people here will say do a swap to B series or K series because they all know money grows on trees and you could **** coins out your ***.

Seriously if you want to do it do it.

 

im gonna do it either way but i mean as far as comparing puttin that head on a dx block or on my si a6 block which would be better?

 

Go for the A6, little more displacement and a world of aftermarket internals. Good Luck.
