Default 30 degree valve

is the 30 degree valve grind worth doing in a stock pulling tractor . i got new kohler valves for a 301 but the machine shop said he had never heard or done that. he said he didn't know if the 45 valve would be right after the grind?

I won't give up angles but I would recommend a 3 angle valve job on the seats . you can nail head the valve by undercutting the head or get some stainless stock altered valves from super cub . I've been playing with cutting the valve head with 3 angles also, it gets a bit complicated considering it needs to match the seat at the middle angle

I think the wisdom was to change the angle on the INTAKE valve only to help with filling a bit more at lower rpm. I think that was from the flat head fords.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
