Question about Cars & Trucks
I'd say that it all depends upon whether or not you have adjustable lifters. All flatheads have solid lifters, but most of the older (pre-50's) flatheads had non-adjustable lifters. Elimination of valve lash was accomplished by welding a glob of metal on the top of the valve stem and grinding it down to the required height. In the 50's, adjustable lifters were introduced, but it seems that at the same time, manufacturers increased the weight of the valves (thicker stem walls or solid rather than hollow stems). If you have adjustable lifters, try .008 on the intakes and .016 on the exhaust.

SOURCE: Valve tappet adjustment
well, I can see ur message has been here for quite some time. Most probably you got the answer to ur request.
I just did the valve clearance on the engine of my SJ413 that has the 1000cc engine of an SJ410 :
When cold: 0.13mm Intake and 0.18mm Exhaust
Engine sounded well and worked fine after that.

0.10 - 0.15mm inlet
0.18 - 0.23mm exhaust
but you must be carefull because the top of the valve seat becomes concave from wear, a feeler guage will not give the most accurate reading, hope i have been of some hel

hi, no not on these newer cars as they all have hydraulic lifters on the older cars you could measure the gap with gauges and adjust to the correct gap but on these newer cars you have hydraulic lifters and it sounds like it could be one or more of these that are giving you the noise you hear.
The problem you have is that you have to replace all of them as their is no way of measuring the gaps to find the faulty one so it can be expensive parts wise but doing the work isnt to difficult but it would be of great help if you got a workshop manual as it would give you a better idea of what your doing and the correct torque settings etc
let me know how you get on or if you need further assistance ok
