Heads issue
First off a 11.1:1 compression motor is not going to work on the street for normal every day driving.If you had a really big cam to bleed off some compression it might work.You could cut some of the dome off the pistons and get it down to 10.5 at max,then its more suited for the street.To save your self some cash,before buying 1500$ worth of heads,tell us what you intend to do with the car ,drag or street,rpm limit,just a cruiser,highway,gear and tranny set up,etc.If the motor is never going to see rpm,s above the 6000rpm range or have a cam bigger than .525,do the work on the iron heads,and have them done by Bobby joseph.You can call him at 1-770-443-8874,and he can explain the good pionts and bad pionts to the iron and eddy heads,as he does these all day long,mrmopartech
