The high volume pump shouldn't give you any problems, if your tolerances are
close the oil will bypass in the pump. As for having too much volume of oil
in your rocker arm area they make pushrods that have a restrictor on one end
that reduces the amount of oil that gets to your rocker arms. This would be
far less work than changing out the oil pump.

Subject: [Tigers] Valve Train
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
