you probably just need to knock the baffles down a little. probably about 1/8 to 1/4". just tell them to be careful. you dont want to smash them in too far.

i don't think it's the ratio. it's the brand/ style. adjustable / non-adjustable.

Some aluminum rockers will cause clearance problems but all of the stainless ones seem to clear just fine. It is easy enough to find out. place the covers on without gaskets and turn the engine over by hand. If it doesn't hit without the gasket it certainly won't with the gasket in place.
The downside to flattening the baffle is it can make it difficult to put oil in.

The harlands will fit
the crower and most others you need to just lay
the covers down take a 2x4 and knock them down
be sure you leave them open on each ends for oil
and PCV to work right
This is why I recomend the harlands you don't
have to do this or adjust them
socaldakota.com has them pouder coated and new
baffles welded in come with new bolt kit and
washers $140

no I have been running mine that way for like 9
years now and its the same on all 3 motors I have
Had to mod them for the crowers as long as the
ends are open a little so oil goes in and the
PCV works

Fed,
I installed a set of the Crower Roller Rockers 1.7 on my 1997 Dodge Dokota. I knew fromprevious posts by Larry that you have to knock the baffles in a little bit. So I took a ruler and measured the before and after measurements to get the valve cover to fit the rockers. knocking the baffles down 3/8 of an inch did the trick. As Larry recommends, you just have to make sure the baffle ends are open to allow the PVC tp work properly. Since you have ordered new Valve covers the point is mute. Maybe this post will help some else who ins installing the 1.7 Crower Roller Rockers.

well Wadak, i didnt buy new valve covers and just
had my mechanic modify the baffels...
heres some news though
i just got my truck back today with a freshly rebuilt engine
and was curious, she sounds if not the same, very close
to the same as before.
does my stock computer have to learn the new
components?
because i can barely tell the ddifference in power
right now but i think that is because im driving no
more than 1/4- 1/2 throttle
let me know what you guys think... ive never had
an engine rebuilt with performance parts
here is what i had installed and done to the 3.9
hughesengine cam HER0814AL
keith black flat top 9.8 pistons
their 1.6 rocker kit
retainers, pushrods, springs
gasket matched intake/removed divider
heads milled

Fed, 2 things. one the motor has to break in. and two, it will take the PCM some time to learn what to do with that new engine.
i would not be surprised if you didn't notice any diff for about 500-1000 miles or more.

daddio,
Once I got my Roller Rockers installed and adjusted, I have not had to readjust them. It's been approximately 30,000 miles since installation. I thin the lockdowns do a good job of keeping everything in place.

Fed,
I would take it easy on the truck for the first couple of 2000 miles to give give everything a good chance to breakin. Yes the computer will have to learn the new settings. This usually takes acouple of hundred miles. After everything gets wears in, it might be a good idea and do a reset to learn the new setttings after wear-in. You'll have to keep us posted on how the new engines feel after having it rebuilt. Just be patient with the new rebuild, it will take time for everything to breakin and adjust. I think Larry normally runs about 5000 miles on regular then switches to synthetic. I would would interested inknowing what your plans are. If you get a chance after breakin, you might to get your truck dynoed. It would be good to know where you are horsepower and torque wise.
Between you and Larry you might have started a trend here. Keep us posted and good luck with the new engine. Maybe your isnt knew but at least it will be set the way you want it. There is alot to be said for that. To me the most valuable vehicle you can have is one that's paid for, reliable and has the performance you want.

i really appreciate your guys replies thanks
daddio and Wadak,
my engine only has about 60 miles on it as of now
and yes i will be driving her lightly for the first
thousand miles or so...
but after the 500 mile mark i'll change the oil then go for
another 1000 and do that again.
this is what my mechanic recommended
ill definately keep you guys posted on results
ill dyno the baby after a few thousand miles for sure
but before all that i need to install my 6a and buy a v6
mopar pcm along with a bigger throttle body to get
the full effect of the rebuild
can u guys give me a rough estimate on how many miles it
would take the stock computer to learn everything?
and do you think its good to open her up after a few hundred
miles (300-400) just to clean it out..?
thanks!

i think you'll find varying opinions on how many miles for a good break in. i'd like to think it would be broken in in about 1500 miles.
as far as the pcm "learning" everything it depends on how far away from the stock baseline you've gone with the engine. the more mods the longer it takes. i think Larry mentioned one time it took a few hundred miles for the pcm on his truck to settle in. 300 maybe.
hope you enjoy it. just don't be too impatient with it.

yeah, i pretty much went from stock, to all that i
listed above soo im sure it will be a while before
the pcm learns everything
and yes i will be patient, i waited 2 months for the
truck to be ready, another two weeks wont hurt!
again do you guys think its good to open her up after a few hundred
miles (300-400) just to sort of "clean" out the motor..?
