I picked up a pair of Pro Comp. aluminum heads from a guy that restores old cars. These heads are like new.The owner that put these heads on just before he sold the car to anouther guy. The new owner wanted the car back to original and steal heads.
They are 119 cc chamber with 300 cfm runners with 2.25 intake valveand 1.88 exhuast valve. Rectangle ports. $850 for the pair
