Is it possible to pocket the block sufficiently to take a 12G940 (head stage 3) and a 276 cam using standard rockers and flat top pistons?
any idea how deep the pockets would need to be or is it just not clever?

any help / advise would be lovely
cheers!

It is possible.
15 years ago i had a 1098 with a 276 cam. I fitted a 12g940 head without skimming it and it was ok.
Put the haed on a table. Check how much the valves can open before it hits the table. If it is 9,5mm or more you can fit it right away. No pocketing needed.

Yes it is possible, but a stage 3 head and a 276 cam on a 998 will make for interesting driving. My 998 with an MG head and 276 cam would happily rev to 8k, but without mapped ignition would not pull the skin of a rice pudding below 3k.
