Do your home work.

I like the numbers Ryan J. gets out of these heads. And with a relatively small runner vol. and valve. Just thought this one would be a walk in the park. LOL. Maybe I'll feel better when my kid rips off a low 10. As for the rockers fitting. I suppose if I bought the stands and offset shafts they'd have worked. Just decided that if robbing off the original I'd use everything. The early 5's had the rocker peds. Or so I'm told.
