Guys, I have been searching a bit - What's the general procedure to replace a worn camshaft in a BRM ? Specifically, how does the camshaft come out of the head? Do the bearing caps unbolt and let the camshaft come straight up? I assume the lifters would pop right out too. Is there anything finicky about the injectors and their rocker arms? I had the camshaft cover off my friend's BRM today and saw a bad lobe (and early silver lifters) but I neglected to pay attention to how it could be removed. Ideally with the head in place and engine still in the car TIA!
