Hello everyone. I'm new to this forum and a new jeep owner. I bought a 88 Yj about two months ago with the 4.2 ba-10 Sahara Edition. I recently did the 4.0 head swap from my 94 Cherokee donor but have a few questions that I can't seem to find the answer on.
1. Which crossover pipe will work to match up my factory exhaust to the Cherokee stock header?
2. What are people getting to block off the EGR hole on the underside of the carb intake manifold?
3. There is a tube that was connected to the right side of the exhaust manifold (4.2) that ran on the inside of the stock crossover to the passenger side and back over again. I cut that pipe to get the stock manifold off the jeep. What is that pipe and can I block it off?
Thanks for the help you guys provided in your head swap write ups.
