Bob,
These heads will and do work with the TPI intakes. All you need to do is drill
and tap some bolt holes in each head. I follow the conversations on
www.thirdgen.org (for Firebird, Camaro owners) and there are lots of people
there with first hand experience with this conversion. I remember reading once
on that site that there is a company that sells modified Vortec heads for TPI
applications... but you'll have to ask around on that site because I don't
remember the name of the company.
Hope that helps you some.
