Here is an interesting statement from David Shealey… thanks Dave
<QUOTE>Having the valve clearance on the high end of the spec, or even 0.001" looser, will change the valve timing such a negligable amount no one will be able to tell the difference. Having them 0.001" tighter than spec. will cause the valve to start opening just slightly on the "clearance ramp", which is a much slower movement than the actual opening/closing ramps on the cams. That is BAD, as it starts the high pressure gas seeping through the exhaust valve at very high speed, which can start eroding small tracks in the valve face/seat. That progresses to burned tracks that mean a valve grinding, or valve replacement will be necessary.
I never hesitated to run the valve clearance between middle of spec to 0.001 looser.
No "feelable" performance issue will result, but will help prevent valves from wearing to below spec before next check.
The valves wear tighter because of the valve face and seat wearing, letting the valve seat lower in the head.
If you ever get one wearing looser, that is a sign of something bad happening, either lifter, cam or cam bearings wearing. Those are worse than the valve/seat wear, as it is much more expensive to repair later.<QUOTE>
The bold comments above tell me, AND with the way you ride Gretchen
… you need to get some smaller tappets and go to the highest gap!
I don’t think you need to measure each and every tappet to see if it is still in spec… because the wear is on the valve face and seat which closes the gap between the tappet and the cam
Looking at the spreadsheet… it looks like you can only re-use a total of 7 tappets you already have.
The four 2.750’s. Those will be for intake 1A &B, 2A, and 4A… AND three of the 2.800’s. Those will be for intakes 2B, 3A & B
So IMHO… You need:
one - 2.750 (exhaust 2A)
four – 2.700 (intake 4B, exhaust 1B, 2B, and 3B)
four – 2.650 (exhaust 1A, 3A, and 4A & B)
NOTE: I also read somewhere that some dealers will exchange tappets (cause they don’t wear). You might want to take six of the 2.800’s and the three 2.850s to the dealer when you go
