My name is Brent Ramey. In1999 I was in a salvage yard and saw the remains of an orange '69 GTO that I later bought for $400.00. PHS identified it as a RA-4 Judge, M-21,4.33 that was built without PS,PB or A/C (no drive train). It has taken nearly eight years to locate all the date coded correct parts. My current problem is that I do not know the correct bolt head markings on the engine. Your picture post of the intake bolts solved one question but I have many more. Would you allow me to take pictures of the bolt heads on your engine? I have to come to Atlanta sometime before Christmas and would do it at that time. I have a flex schedule.
