7120 head Improvement
Posted: May 10th, 2018, 12:51 am
I am new to this Jeep engine rebuild stuff and I hope everyone will be gentle. I am wanting to build a Jeep Stroker. Probably a 4.7. I have a 2002 Jeep Grand Cherokee block and it is stock as of right now and has had nothing done to it. I thought about the Edelbrock head but I can’t justify the cost just to get a few extra horses. I have researched the 7120 head. Is it worth doing some minor porting and polishing and getting some bigger valves. I would like to get Harland rocker arms installed on it and I was planning on getting the Banks exhaust manifold for this build as well. I have a 2002 intake manifold and I do plan on port matching the intake manifold for better airflow. Any thoughts or opinions about parts or companies to get parts from or companies to stay away from are appreciated. If anyone knows of someone who does Jeep head work as well will be appreciated. Thank you for your opinions and ideas.
