Reducing oil to the camshaft?

anyone here got thoughts on reducing oil falling on the cam?

Im interested in oiling mods such as chamfering the man oil drains in the valley pan so that oil runs back along the under side of the main valley drains as to not introduce air into the oil by falling directly on the cam shaft.

covering the main oil drains in the valley with screen and drilling oil drain holes in the depressions near the lifters?

I realise the cam bearing are not fead by direct (high pressure) oil injection and need oil for lubrication and pulling heat off the cam.


Firesuit and Nomex jockys on.

Thanks again for all the time and advice.
