hi stewart. are you finally up and running now ? i remember that when i did my belts last time, when it first started up , it sounded very rough. wrapping and tapping quite a bit, in fact enough to make me switch off !! then after a restart it improved steadily and by 10 mins later ran as sweet as a nut , and has since. i think the engine needs to self adjust its anti knock system and timing set ups as it does this itself. just wondering how you got on after all your hard work , hopefully a good outcome with the replacement heads and camshafts . an update would be nice ..
