View Full Version : Head questions

03-26-2004, 05:25 PM
I just picked up a 3.4 with 35,000 miles on it and was interested in upgrading the Heads. My question is how much can I do to the Heads before I need to have my PCM flashed or upgraded? I only want to upgrade as long as I dont need to do any computer work. I already have the PP Upper and Lower intakes and TB with a CAI. If this is possible to do without computer work does anyone have spec on the heads and a list of parts I need such as valves, springs, pushrods etc. Any help would be greatly appreciated as I am excited to get this project going. Thanks in advance. :thumbs:

I was wondering the same thing, might do mine in the summer.
Are you porting yours urself, or are you getting a local shop to do it, or buying them from someone like apoc or dr speed ?
Just wanting to know what i needa tell the machine shop, if i decide to do it.

I do have a local shop that will do the work. But I'm just to worried about doing computer work, Just never seems to work for me and I dont feel like going through the same problems I had with the MAF sensor.
