We should have a top swap section between the supercharged and the N/A sections... :grin:

Anyway. I am planning on doing my swap over the winter on my 04, and I know I am going to have to replace my heads with GTP heads, but I was wondering if I could use series 2 heads or if I need series 3.

A search on Car-Part.com came up with either, so I wanted to be sure.

Or should I just make things simple and get a fuel log setup?

You can use either head. They are the same, from what I remember on a GM part number. An ASSEMBLED head IS different, but either will work.

Slight correction...and no big deal...they are 1.66:1. Strangely enough, the part numbers for like '95 and up are the same.

Can I reuse my GT valve covers or do I need different ones?

Yes, different ones. The S/C ones accomodate the injectors.

How much u think you will spend on the swap ? Is 800 installed with parts a good deal with a custom tune ?
