So, I will schedule a return to the dyno.
-New exhaust. Car is 10x quieter and also stronger with the OBD2 headers and smaller diameter down pipes.
-Static cam timing. Intake cam had been retarded about 8 degrees. Dead-on now.
-VANOS seals. They broke into pieces when removed. Intake cam was not advancing nearly enough and was hard to control.
On the negative side I added a MAF which I didn't have before.

Well since the OP said it was OK, here's my build. I won't be doing a build thread of my own. However, I will answer any questions that might come my way.

Originally posted by ForcedFirebird View PostPrimaries look a little large, but the design is bang up. People tent to over-size headers - but keep something in mind - NASCAR use 1.625" primaries (stepped up after) on a 4" bore and make 100hp per cylinder.
That photo was just to show the "equal length" style/design that my fabricator Zack envisions.

Mine will be stepped primaries, 1.5 x 9"/1.625 x 9"/1.75 x 9".
See above.
