I have posted on this before but was wondering if anyone else runs this combo.I have a 351w bored .030 running speed pro forged pistons and I am installing a F303 cam and I have 1.7 RR,along with the edelbrock performer heads.Will I have any valve to piston clearence issues with this combo?I primed the oil pump and spun the motor over on the stand and I am not hitting the valves or anything like that.Thaks for the help in advance.
