I emailed Tom Langdon, and he says that there were no roller rockers that came with the business, when he brought it 10 years ago.
Maybe Dick Larrowe has/had some, as they were supposedly tooled up for. Any-one going to ask?
JD, are those Thomas Hi-lift rockers useable on late 235/261 engines? I was of the opinion that they suited 216 heads only.
