Welcome and congratulations on the 2Stroke kit purchase. There is no reason that you could not build the kit chassis into a head. Using a design similar to the Fender 6G15 reverb, the 2Stroke chassis would work great.

Andy would be best to answer the kit questions but I’d advise you to put insulation on the component leads on the back of the eyelet board so nothing touches when it’s mounted to the chassis.

Good luck
