New hammer what will it run?

I don't really enjoy building them after about the third tube I get bored.Spintek used to make 1 7/8×3" for later Dakotas and was told they may work on the earlier ones but not sure.
I considered the s10 headers and just weld mopar flanges on them but the s10 I saw them on engine compartment is way different.
I used the stock four cylinder five speed transmission cross member.
