I've never rebuilt an engine where stock length push rods did the job. I'd
suggest you buy/borrow/make a push rod length checker. If you have the
tools, you can make one from an old push rod by cutting off the ends and
drill/tap them to accept a piece of all-thread. Most cam grinders carry
pushrods in a variety of lengths. Hardened pushrods are not normally used
for additional strength, but to prevent push rod galling when used with
guide plates or early 289 slotted heads.

have a 302 that we did a full rebuild on 2.5 yrs ago.. We just pulled
the heads and are installing roller rockers.. I find that THREE of the
new push rods are severely bent.. one so bad its been rubbing on the
sides..
there is less then 3000 miles on the engine..
I am replacing all the push rods with a set i bid on ebay that was
"supposed" to be  4x hardened.. it appears that they are just "hardened"
and  are not chrome moly  4130 one piece rods.  they however are better
then "stock" pushrods
and are "black" in color not chrome like the old set was.
the engine is not built for high revs in the 10k range but in the
4000-5000 range.
the engine is not runing alcohol.
question #1.. should i stop and get the GOOD  $80. ish push rods or go
with the set i have..
question #2.. WHY do pushrods bend.

This is in reference to #2.

A 302 of mine lunched a valve while idling in the driveway.  I couldn't
keep the rocker nuts from backing off.  They kept backing off and
before I could figure it out, a few rocker nuts backed off enough to
allow the rocker to move sideways (effectively defeating the rail
design of keeping the rockers aligned).  This caused bind and every one
that binded bent a pushrod.

At the time, I couldn't tell from the idle that the rockers had backed
off that much.  It just happened.  I gave the motor away.

Has the motor sat inactive in humidity for any length of time?  A
rusted valve guide casing a sticky valve could cause the bent pushrods.

nope not sitting a long time at all.. runs at least once-twice a month..
did a full engine rebuild not that long ago.. pistons look good.. am
installing guides and rollers and have repl the cam followers.. i do not
know if the bent ones were on the intake or exhaust.. engine ran
actually pretty good also..  the rocker nuts were a bit loose on two
rockers.. that is why we decided to pull the heads..

I ordered a radiator.com an advertiser for the list and I can tell you I
am quite happy with it.  I got a good deal on it and it was free
shipping.  They were very helpful.

You need to contact:  http://www.ford-trucks.com//lc/lc.php?action=do&link=http://www.pushrods.net/  They will supply you with
exactly what you need.  They are the best!

Why do push rods bend?
Because the force that is generated by the cam lobe is not being transmitted
to a valve that can move.  Something on the end of the pushrod that is away
from the cam stopped moving for some reason. Rocker arm jammed. Rocker arm
geometry is WAY off.  Valve stuck in the guide.  Valve hit the piston.  Push
rod jammed at some point. If you stop one end of the push rod and push on
the other something's gott'a give.  I once bent 3 P/rods simply by
restarting the engine!  I never did figure out what happened!!  I took
everything apart, found nothing wrong, replaced the pushrods (all of them)
and the engine raced for another 5 years with no complaints!  Go figure.

Good Luck.

If you added stronger springs and/or changed the rocker ratio in the process
of installing the roller rockers or you improperly installed some of the
rockers and got them binding at some point in the lift cycle you will bend
stock pushrods and most high quality ones as well in the latter case.  And
if you installed a higher than stock lift cam in the rebuild with stock
single springs you may have what is called "Coil Bind" which is very easy to
inspect for by simply rotating the engine and watching the springs.  If they
go through the whole cycle without ever running out of space between the
coils then you should be ok but remember that hydraulic lifters, though
theoretically oil tight, will bleed down slightly when being hand turned so
allow for a little margin.  You should aways check for clearances on a
running engine for that reason.

If you have access to the PowerStroke Registry, they did an article
on this guys truck a few issues back.

The 5th wheel is a modified Teton Homes unit. I think he modified it
so part of it functions as a garage to haul his Harleys.
