I may have a connection to buy black diamond 7mm. stemed valves and guides for a very good price. Can I go any larger on the intake valves without changing the seats? If so how large can I safely go? Thanks guys

Valves

Black Diamond (Kibblewhite) is what we use here. Top shelf products.
1.900 on the intake,(you can squeak a 1.940 turned down to 1.915) and 1.650 on the exhaust is about all you can go.
