Think you may have done it wrong. One carb is fixed and the other three are balanced individually to that one. I'm sure there is quite a bit of discussion about this as things like the Haynes manual are wrong.

A good article here about how the carbs are not balanced as pairs, but individually to carb 4. Also stating how the Haynes manual is not correct.

By the book you should have done the valve clearance first, as also those influence the gas exchange of an engine.
Except a good set of short valve gauges no special tools required.
New valve cover gaskets + 8 bolt seals could come handy.

Don't forget to plug the bottom oil drain of the heads; dropped shims would fit through there and end up "somewhere" in the crank case/oil pan...

check the old valve clearances and note them down
remove the cams, pull the buckets and measure the shims
calculate the difference to the ideal clearance and select new shim accordingly
re-assemble, rotate the engine through by hand and check valve clearances again
