Hey man, I have 94 GT and noticed in your mod list that you ported your heads and intake by yourself (DIY). How did you do this? I inquire b/c it only cost you $18 and I recently purchased a 65mm TB and I want it to match with the 60mm stock intake. Any info/help would be greatly appreciated, thanks

The site
http://www.diyporting.com was very helpful and I followed their guides to intake and head porting. The $18 was the cost of the stones that I used for the port jobs. There was no additional cost because at the time, I had a blown head gasket (stuck thermostat was the cause) and the heads had to come off anyway. I just took advantage of the opportunity to port the heads/intake while they were off so I could gain some performance, and it turned out to be a very good decision.
I also matched the opening of the upper manifold to my 75mm TB. The stock upper manifold opening is ~68mm IIRC.
