Randy,It's difficult to say with certainty, but they look an awful lot like the FRPP 1.6 Roller Rockers on my 347.Are there any markings on them? Mine have the Ford logo and clearly state "1.6" among other things. Are these your rockers or someone elses?
Where were yours marked? There is no markings on the top sides on these.
