Shorter push rods for a 1275??

[Paul V]

I have taken the old head of my car today, just fitted the new high compression big valve head along with high lift rockers but I can’t adjust the rocker enough to get the valve clearance. Wondering if there are shorter push rods available?

The head was very high comp when it was first measured so has had more taken out of the chambers to drop the compression to a reasonable amount. It also looks like the top of the head may have been machined at some time as the 12G940 text has the top of the casting missing. Is there any benefit to doing this or would it just be to get all the gasket faces clean?

I have fitted standard rockers for the time being which have about 1-2 turns spare when adjusting the valves but I would like to use the 1.5 rockers, what is the best option? Shorter push rods or packing? Also do you know where I can get either?

I’ve been told that grinding the push rods down slightly might be an option.
