1104 on the case halves (or its current iteration), your choice on the cam towers. We have had good success with both 1104 and 574 there. But never ever had a case leak with 1104 on the case.

To the previous poster that thinks Wayne's recommendations are gospel... Build a few engines, find what works for you. You MAY find some things in that book that you would never do.... As an example, we, like many pros in the industry, would never put RTV on a case bolt washer. Its a great book, we reference it often, but build a few motors and learn what it is right and what is.....

Read the thread. There is so many great recommendations. Pick your sealants, and go with it. There is not one solution, but pros (who have actually built many motors) have taken the time to give you their experiences.
