You can helicoil the pump end of the lines, but you have to install the coils manually, with out the tool.
I did this by screwing helicoils into an old 14mm mag-style lugnut, heating to a red glow, allowing them to cool and removing them from the lugnut.
I then trim to fit the line end, then screw in by finger with a dab of loc-tite.
It's a time-consuming pain in the ass to do, but a very cheap solution.
A non-intercooled ('89-early '91) pump and any VE timing case fits the 24 valve just fine, but you will need to jump a tooth and retard the pump clear to the studs for stock-ish timing.
The reason to do this is because the linkages will hit the head.
A pic of how I ground on a head, to help clear the linkages for potential timing advance later (note: the corner and bolt didn't need ground, but this was the 1st attempt.):
