Could someone respond as to whether the "Performance Tuning the Sunbeam
Tiger" book contained a recommendation on what maximum camshaft lift the
stock 260 would tolerate without valve to piston interference or whether
another information source has that maximum lift number?

On page 41, it states: "when you pick a camshaft for the Tiger and plan to =
use the stock flat top pistons, the valve-to-piston clearance is a limiting=
 factor. The following rule of thumb should be used in picking a camshaft f=
or the Tiger 260:=C2=A0 Maximum lift: 440"=20
Maximum overlap:56 degrees. The LAT-20 Sunbeam cam exceeds the lift, but no=
t the overlap. Therefore it is usable in the Tiger with flat top pistons, p=
rovided that you are using the stock cylinder heads with original 1.67" int=
ake valves. If you are running larger valves, then even with the=20
LAT-20 cam you will probably have to notch the pistons for valve clearance.=
