Is there any specs on the groove for the grooved camshaft - depth and width? What is recommended? Another related matter - the holes in the center bearing that supplies oil to the rockers - should they be as big as the holes in the block? A friend told me that one of the oil passage holes in the cam bearing (the one toward the the crank?) overlapped the hole in the the block leaving the oil passage about 1/3 the intended opening size. The other holes in the bearing aligned ok Should the smaller hole be made bigger to the size of the block? Thanks
