hmmm,i give up

didn't someone mention this recently, and one answer put forward was a second rocker cover gasket to increase clearance?

Had similar problems with my cars in the past and one solution (not successful on every car mind..) was to put the rocker box on loose and when tightening up push it as far back as you are able towards the carbs. This might work. If not superglue 2 gaskets on to the cover. Not ideal but better than clattery rockers. A tin rocker has no real leeway to machine anything out.

Why not bin the rockers?

1275 pushrods maybe.

I thought A+ rocker covers were essentially the same shape? It must be something other than the cover causing the problem.

There's no way you can fit 1275 pushrods in a small bore unless it's got a massive stack of shims under the rockers posts.

All I can think of is that the nut on the rocker is bigger on the sintered version.

its an early rocker cover,,it has bowed in the midle causing the height to decrease slightly

i noticed on further removal of cover
