Engine Valve cover/ intake studs and other stuff

I have studs for the valve covers and they definitely make it easier dealing with them.

The intake alignment studs are awesome! I just bought a couple of bolts at Lowe’s, cut the heads off, and rounded top off. Works great for re-installing the lower and the upper.

Yep, 5/16-18 threaded rod at Lowe’s about 3 inches long. 73 cents each.

Do tell how it works out for you. thinking of doing the same.

@Potomus Pete, here’s the email I got back from the shop I sent my injectors to (injectorrepair.com) I should have the injectors back by Monday or Tuesday. One week turnaround.


Your set of eight OEM Ford injectors flow tested bad right out of
the box (after an initial exterior cleaning / de-greasing). During the
initial flow test; one of the injectors was significantly clogged. It
was not the injector that you had labeled #8. Good news was that they
all held pressure (no leaks).

The engine would not have been able to run well with these
injectors.

I see this all the time esp. with engines that have sat for a
long time unused, or were run with E85. After an extra long session in
the cleaning tank and back-flushing, I was able to get the injectors to
like new function (good spray pattern and flow rates).

An Injector Flow Balance of under 5 % is considered necessary for
proper engine performance. When I sell refurbished sets, I try to get
them flow matched at one to three percent flow balance.

The closer the flow rates of the injectors are to each other, the
better the engine will run, and the engine will run smoother and get
better miles per gallon.

The microfilters were clean. After removing the microfilters, the
injectors were clean on the inside. No noticeable debris came out of the
injectors when I back-flushed two of the injectors. The discharge tips
were clean for a used set of injectors.

Attached are pictures of some of the multiple flow tests I ran on
your set of injectors. Picture # 1269 is of the initial dynamic flow
test (before cleaning). Picture # 1273 is of the final flow test after
the ultrasonic cleaning sessions. I ran all tests multiple times.

Your injectors final flow tests improved, and were great !! The
dynamic flow test ( 12 ms pulse width / 2400 rpm / 25 seconds ) had flow
rates of 48 to 49 cc.s across the board. The injector flow balance is
now very close to
2 %. Good to go.

They all performed flawless in all the tests.

All of your injectors held pressures over 80 psi without leaking
a drop, and their spray patterns were good.

They are 100% ready to be put into service.

The valve cover stud kit was worth the money in my opinion. A bit fiddly with the extra washer and nut, but it made getting it all back together so much easier and not worry about pinching the gasket.

That is an impressive report out, from the injector guy!

I know, right? It was another reason why I sent them out. I wanted to see how bad they were before I just tossed them. Can’t wait to get it all together again.

Update: Got the car back together, no leaks from anywhere and it runs like a totally different car. So much more responsive and interesting to drive, even with the 2.73 rear end! But that's down the road a long time from now.

Buying the "alignment studs" (5/16-18 threaded rod) from Lowe's for help putting the upper intake on was a worthy investment, as well as the ARP stud kit for the valve covers. $30 between those two things for not pinching a gasket and having to do it all again was worth the money to me. Having the injectors professionally cleaned, repaired and flowed was probably some of the best money I've spent on this car so far.
