Good luck
Mines in bits at moment broken header bolts and rusted (valve bolts, not yet got to yet but will be trouble.
If I was you I would sort out now before summer, replace all bolts with stainless and copper slip.
You don't want to be doing the job when it's sunny. Like today :-(
If your taking headers off might as well do the AIS at same time.
I'm tapping mine M8 and stainless grub screws with high temp thread lock.
Or you can go the cap route.
