Valve Springs for break in......?

The lift isn't necessitating a lot of pressure, so just run the recommended spring , rev it between 2200/2800 rpm ,fluctuating, and relax. Mainly people have trouble with fuel, burping the cooling system and timing...so keep an eye on those and have a garden hose ready, fill the bowls with fuel through the bowl vents and have the timing light hooked up and timing quickly set to around 35 degrees total/full advance or what was "recommended by the builder"
