SpeedMaster Head- Rocker Options/Questions

madhatta360 said
1. Can I run stock rockers/rockershafts/pushrods with the Speedmaster heads? I'd like to consider upgrading the rockers/pushrods- whats the best options out there that are compatable with SM heads and simplest to install.

2. I will be using the springs (specs below) from my J heads which match the Crane Cam, will there be any potential issue with that on Speedmaster heads?

You can run the stock rockers on them, but personally I would upgrade them. Pittsburghracer should be able to advise you on what fits your build/budget - you are in good hands. As others mentioned you will be up for new pushrods in the right length. The speed master heads take a taller spring than the standard head (around 1.8" installed height vs stock 1.65")
