Will Vortec heads bolt up to the TPI intake?
Will Vortec heads bolt up to the TPI intake?
Will Vortec heads bolt up to the TPI intake or do I need a special base because of the tall intake runners on the heads?

Not as it sits. I think I read about someone here having the heads redrilled and he did something else to get it to work with the base. Maybe it was adapters. Hopefully whoever has done it can offer some advice.
There is supposed to be a vortec TPI base coming out, but I dont think anyone is holding their breath.

The bolt pattern is competely different, and the intake passages are somewhat different. You can have the heads modified to work with your stock intake, or you can wait for Scoggin Dickey to come out with their Vortec TPI intake, sometime this year. Dont forget the Vortec heads do not have EGR passages for emissions compliance, if that is a concern in your area.

Is the computer going to throw any codes without the EGR working?

Im the guy who has aready used the vortec heads.You can modify your base to work and if you use a vett base you can still have the egr but you have to change to the vet egr set up if you do not use the egr you will get a code 32 I have made 2 of these set ups now and both are doing fine my car uses the fast burn heads wich have the same style intake ports as the vortec heads if you rilly want to know how to do it give me a E-mail or if you want I have one that is already modifide and I was trying to sell it for 150 I have that much in to the machine work that had to be done to it but no one seamed interested so I stoped trying to sell it.My e-mail is 87gta@altavista.com I have a few pics I can send you if needed.
