I once built an Lt-1 350 small block especially for propane, raised the compression to 12.5/1 installed hardened valve seats with stainless valves and got rid of the valve rotators.

Engine was installed into a 69 GMC with a turbo 400 behind her, loved that engine which eventually ended up installed into a 1956 International 3 ton. Ran propane exclusively and not set up for dual fuel.
