Now there is Burton BF134, hard pad followers, hd retaining clips and new oil pipe in the head. Also already did the brake-in for the cam (2500+ rpm for 20 minutes).
Old Pipercams is clearly a waste, it had already ruined one follower (reason for the tapping obviously). Third exhaust follower, the same than in the engine it was before.

Was able to keep the heat down enough with the radiator fan jump wired to be on all the time and inner heater blowing on full + this awesome desk fan (dunno if it was use at all but just in case

)
