Head question

I know I should know this by now, but are all 12 valve heads the same from 1991 1/2 and up? I know the P-Pump engines require different injectors, but are the injector hole sizes all the same on the intercooled engines?
Thanks,
Mark

Yes.

The 2nd gen heads may not have the boss drilled and threaded for your throttle assembly bracket, but the boss is there and you can drill it.

Thanks much. Now I have to find a rebuildable core!

Second gen heads are also notched for the P-pump . Check out Alabama cylinder head. Got a complete head from them a couple years ago for $400.00 it also had the beehive 60# springs on it.
