Karl, et al,
By "high output oil pump" you probably mean a high volume oil pump, not a high
pressure oil pump. They are not the same and there is probably no reason to
have a high pressure oil pump in such a relatively mild engine. I don't think a
high volume pump will give you any problem, but just watch your oil level.
I have heard that some roller rockers will not fit under the stock valve
covers, with or without, the deflectors, so that is something you might want to
check on with your the Comp Cams rockers. I have Ford roller rockers (which I
think are made by Comp) on the 302 in my Tracker, with no deflectors, under
stock finned aluminum "Power by Ford" valve covers without clearance problems.
I don't know about changing the oil pump with the engine in the car since it
has been many years since I've been under a Tiger.
Hope this helps,

I installed a high output oil pump in my stock 260 when having the engine
rebuilt. Now I'm having second (and potentially expensive/delaying)
thoughts.
So the 260 is very nearly stock, except for the oil pump, hardened valve
seats, valves, springs, hydraulic lifters, roller rockers and pushrods. All
are mid performance items from reputable/ Made in USA companies. Stock block,
heads, oil pan, cam, crank etc.The instructions for my roller rockers (COMP
Cams) says that if I put in a high pressure oil pump I need a "set of valve
train oil deflectors to put over the rocker arms, ensuring that the oil does
not shoot over the top of the rockers." To avoid galling of push rods, rod
seats, pivot ball and rocker.Looked up valve train oil deflectors and have
only found for "Chevy and Ford 302" from Moroso. Not only is that not my
application, the listing says that extra clearance may be needed at the valve
cover and I REALLY wanted to use original 'chrome' valve covers. Not to
mention, the pictures of the deflectors look as though they are nearly the
same distance from the rockers as the valve covers would be...I also read
somewhere some other, maybe related, negative comments about high
volume/pressure oil pumps. At this point I'm almost tempted to change it out,
but would really prefer not to. It is my understanding that the oil pump rod
uses gravity to stay in place. Is it possible to replace the unit from
bellow? Without removing timing cover/ bell housing?I appreciate any insight
offered.KarlMK1
