Seen two vids on the new mopar small block trick flo heads, the rockers beating the tops of the retainers and one broke valve.
Wonder what the mis match in parts was here?
The only rockers I would have any real “expectation” about fitting those heads, without needing modifications to something, are the HS part numbers recommended by TF.
Anything else should get extra scrutiny(although they should all be checked).
If there is evidence of contact between the rocker and the retainer.......IMO, that’s on the one doing the final assembly.
