These are the photos of my bench machining setup & the job I partially finished on the RB30 head.
Can you guys have a look at the photos and advise me whether I need to machine it further?
I'm particularly concerned about the pitted/porous surface around few of the water jacket lines(see photos).
I used 320 grit wet sandpaper with a bit of WD40 sprayed on it to machine the cylinder head surface.
