Swapping distributor with hei

[ben82k10]

I have an 82 k10 with original 4.1 250 inline 6. Would it be worth switching to hei? Also is it 1 for 1 or will other mods need to be done?

It should be HEI already.

Anything 75 and up should already have the HEI ignition if still the stock distributor.

Agreed, yours should be HEI already.
However... I will add that my '82, although it was HEI, it had electronic spark control from the factory, which included the distributor. I couldn't get my fresh rebuild to time worth a lick with that thing... so I ditched it, and purchased a standard HEI distributor (aluminium variety) which removed the need for the factory plug for the distributor.
