Header Suggestions?
I have an '87 IROC-Z 305 TPI that I want to buy headers for. I was wondering what type of headers would be the easiest to install with a stock y pipe. Also, what brand is the best and which will increase horsepower the most while still passing emissions? Thanks for the replies

Dyno Dons are the best IMO, but Hedman and Hooker make good kits for our cars....

Dyno Don with his Y-pipe is the way to go, trust me.
