Yella Terra YT6000 and Rover p6 rocker boxes

[ratwing]

Does anyone know if YT roller rockers fit under these rockers boxes? (the rounded ones with grooves running front to back and Rover in the middle)
If not, is there a supplier of spacers? I have searched but no luck so far.

I've used them with two gaskets...unless you want the aluminium spacers...

I’d prefer to use spacers but so far have only found some made by Medice in America but they’re about £220 inc shipping and then add import duty etc and it’s just too pricey unfortunately.
It’s looking likely I’ll be gluing some gaskets together too then.

I think someone does a set of adaptors to fit sbf rocker covers ...
