When I rebuilt my 583 the mains are in excess of £100, angular contact C3 grade IIRC. No gaskets needed, use threebond.
Big end shells £29.60 ish, valve 1/2 rings £1.58 x8 Several rubber O rings at pence.
I just remembered I did put some cheap mains in on the first rebuild and knocked them out at Snetterton, real bad vibrations. So bit the bullet and bought OEM.
