Once I get my motor running smoothly I'm going to look into putting new heads on the motor. The specs to my motor are in my sig. Which heads would be best to replace my stock p/p heads with???
If you have pistons that are notched for valve relief then you can go with a head with a bigger valve. if not you will hae to go with most 165 intake runner heads. they usally bolt on stock piston applications due to the 1.90 or 1.94 inatke valve size.
