Your tappet clearance for exhaust is out of standard because according to the manual for intake should be (0.18 -0.23 mm) and for Exhaust (0.30-0.35)mm. Please redo the exhaust because that cause tight clearance.
@@samanthadeochoa5701 Diameter for K6A is standard to all valve tappet we are talking of clearance using feller gage, if measurement not correct will cause noise to engine running and will overheat. Your intake is correct but the exhaust is wrong.
