Small block rockers?
We had to use lash caps on the Speedmaster heads with the Comp Cams Ultra Magnums. Didn't know about B3. Hmm.
The Comp rockers are a good choice. I prefer the option of higher ratios not available from Comp, though.
Just an FYI for those interested, adding lash caps with a roller rocker will actually make the true running geometry worse, regardless of where the pattern is on the valve tip. See our tech articles for more info.
Also, a steel rocker has a much longer fatigue life than an aluminum rocker. If you want to drive the wheels off of it, and have low maintenance and long life, a steel rocker will last much longer.
Lastly, we will not make geometry correction kits for Speedmaster/ProComp heads, as manufactured. We have a file with a bunch of broken rocker shaft photos, due to the incorrect machining of the shaft mounting radius in the pedestals. That allows the shaft to rock in the saddle, causing the bolts to loosen. Only if this machining is corrected will we make geometry correction kits. This is not new, and has been known for years to be an issue.
If anyone has questions, after reading through our tech articles, feel free to call. I would be happy to provide an explanation to answer those questions.
