Stick to what fits, not what's cheap.

While that is true, the headers fit either engine. The exhaust bolt patterns are the same and both have "D" exhaust ports. There are more differences in the chassis's then there are in the engines, header wise. It's done all the time.

RACE ON!!!

Exotic Muscle, Hooker, Tpis, all make headers that fit without major problems.

The 91 headers will bolt to the heads, but you dont use a Ypipe and they dump differently to the collectors, that will cause fit issues.
