I am running the TA Perf low profile cast aluminum covers with RJC spacers to make sure I have clearance over the T&D roller rockers. I removed the metal evap shield, and I have plenty of room to remove the covers, even with a pair of HR poly engine mounts. I love the TA covers, as they are quality pieces. I probably have as much or more room now as with the stockers with the shield in place with my clapped out stock motor mounts. Thanks, Rudy.
