I was surprised in the end after all the doom laden comments on the rocker box fitment. I didn't have the comb and kept it simple.
Undid the rocker adjusters and wound everything out. Stuck my gasket onto the rocker box first with 'Permatex Aviation' gasket goo, very much a Wellseal type product. It doesn't set but goes very tacky if you let it dry. Dropped my modified VW pushrods into the followers checking everything was seated properly with a spin of each pushrod and a gentle lift, you can feel the suction if the ball end is properly in the cup. I had prepared the rear studs earlier with hex key sockets in the end so they were engaged but sitting low which helps when maneuvering the RB into place.
I sat the pushrods into what looked like the best orientation to match the rocker cups and then fiddled the RB into place. I then found I could find each pushrod with my fingers and feel that the ball end was in place. I even deliberately misplaced one to feel the difference and you can!
Then took up the slack on any tappets that could be snugged up just to hold everything and then lightly hand tightened the holding down bolts and gently turned the motor over (plugs out) making sure each pushrod stayed engaged, again by feel. Once the RB was fully down I wound up the rear studs and fitted the nuts then the front nuts, which are tricky but glueing them to my finger with a dob of grease seemed to help.
Then it was a case of turning the motor over and going through the tappet setting procedure, torquing all the fasteners, then repeating the tappet setting and finally tightening the locknuts. All done with no comb, rubber bands, mirrors, bits of wire etc. really simple but to be fair I am still pretty flexible and have long fingers!
