I'd agree with Bitsa in that it's easier to check and correct now rather than further down the line. Looks like you're getting a nice rebuild done there and would be a shame to have to pull it out later to correct something that is relatively easy now.
Just a small observation about the gasket sealant in the pictures, I always try to get the absolute minimum on there so that none squeezes out and gets into the engine when tightened.....the particular risk is getting it into the oil supply routes to the head and starving the cam area of oil.........you need to be aiming to look like the glue on selotape if that makes sense, and if the sealant (looks like Hylomar) is too sticky you may need a new tube to get a very even spread or buy it in a spray can to get a really thin coat.
