These are very nice breathing heads about 1500 miles on my souped up 312. Going to Aluminum Heads John Mummert Y Block guru did the pocket porting and valve job. Intake 2.02 Exhaust 1.60 I did some port matching. These are very nice heads.
Please check shipping. Heads weigh 60 pounds each packaged. Also included are ARP Studs and ***orted hard ware
