Oil consumption and ticking after cam swap?

Good point. It doesn’t seem to run like it has a vacuum leak but definitely a possibility I suppose.

I guess I should’ve mentioned I got the matching springs and retainers from Hughes. I was told this setup would be good go as far as coil bind and piston to valve on a stock short block.

how? coil bind I can understand but how about retainer to valve seal? That is a pretty fixed dimension. IE, how much valve stem is showing under retainer? Is it gross lift inches plus some clearance? Im not a magnum guy but if someone can tell us the max lift cam they are running ona stock magnum head, then we could determine what the max lift available to stock valves and guides is.
