so would it be better to swap the head too since the 91 is not intercooled.

if the 91 is non initercooled than the pistons are different than the 95's

also the head on the non intercooled 91 will need 9mm injector tips

Correct from what I know, the non IC pistons and head design are different. you could check on compD to see if theres any gains to be had using the non IC'd pistons.
