I recently purchased a 69 440 engine w/ Edelbrock performer RPM heads. I believe the heads are 10 years old. Does anyone know when these heads came out and if they have changed at all in the past 10 years?
Thanks Donny. I read an article dated 2001 referring to them as the new Eddie heads. I guess that would make them new at that time. I was wondering if they had been upgraded from the time mine were made, but it appears not. Thanks again.
Not to my knowleadge, however, tech at Edelbrock should be able to tell you if there was any changes that were done. There E-mail takes 1 - 5 days to be answered in most of my exp. with them.
