Break in after top end rebuild?

[addisonsan]

Just put in new cylinder head, camshaft, cam chain, tensioner, guide, valve cover. Do I need to break it in? Only took the Pistons out to change the gasket and honed the barrels a bit before I out me back in, they were in good shape.

Yes you need to break in the cam. Use good oil. Don't let it idle, pick up the rpm right away. Oil pressure is your friend.

Ok cool. So no need to keep it under 3000rpm like when you do the Pistons?

Whoever told you to keep your engine under 3000rpm when breaking in cylinders has a lot to learn
