I’ve used the Crane golds on stock heads, stage 6’s, Indy SR’s, Indy EZ’s, B1/BS, and RPM’s........no problems with the fit that were serious enough for them not to be used.

Plus...... they were pretty affordable too.

My go to replacement for them are the Mancini rockers, but I haven’t had the opportunity to test fit them on all of those applications.

The solid spacers between the rockers that the Mancini rockers use aren’t as universally install friendly as the springs that came with the Cranes.
