I’m not going to comment on another shops findings.
I’ve been preparing BBM Ede heads since they first came out about 20 years ago.
I’m pretty sure I was the first one to post independent flow and dyno results for them on Moparts back then.
I’ve done over 130 sets of them.
I’ve seen nothing in any of those heads that would keep me from using them in the future.
I understand and respect that. As far as castings, have you seen much difference between the E-street and RPM ? My biggest concern was the fire ring falling inside the chamber on the one cylinder, but I'm not sure of the gasket used....
