I removed the valve cover and cylinder 1 and 7 intake rockers were
completely broken off! Now these are the stock stamped rockers being driven
by a .512 lift cam and held back by stiff RT springs. Perhaps these rockers
simply couldn't can the pressure. Any other ideas why these would fail?
Also, since these valves are always closed, shouldn't I have seen full
compression on those two cylinders?
If the intake isn't opening it can't fill the cylinder.....
