Header install question
First off, I drive a 1988 GTA with 5.7L
Just got finished installing some SLP headers (took about 9 hours) and when I took it out for the test drive, it was idling really rough like it had a huge cam in it and also it felt like it didn't have power brakes. Had to put the ****er to the floor to get it to stop. Checked for pinched lines and would cause. Thought it might be a vacuum leak but not for sure. Any suggestions would be great.

That defiantley sounds like a vacuum problem to me. If you breaks didn't work that good and it was running really rough? Sounds like you might have knocked a vacuum line off somewhere.

Found the problem. I had left off the brake booster vacuum line to the plenum. Yeah they were 1 3/4 SLP's. No real problems installing them. Only problem was the far rear bolt on the pass. side of the header. Was just hard to get a wrench or socket on it.
Took us about 9 hours all together.
