"For you are an engine holy to the Lord your God. The Lord your God has chosen you out of all the engines on the face of the earth to be his engine, his treasured possession,"

Hate to say it, but that could just as easily apply to a 429 Boss or a 426 Hemi. Take care. Tom Worthington

And also the ol "toss gaskets in with metal because fuck it" trick. Off to auto zone.

That area doesn't seal anything

True but having broken one oil pump housing, can you blame him for not wanting to take a chance at all?

How many guys here would use that gasket?

I wouldn't.

I wouldn't.

As long as there isn’t any of the gasket missing , I’d glue that fucker in place and bolt er up

Just fucking send it!

Just fucking send it!

Another 4 day delay.

Buncha slackers!

I habe done worse to gaskets to make them fit. Wouldn't hesitate for a second to use it

I usually make my own so I guess I'd make another one, lol.

Lifter cleaning as per instructions:

Mineral spirits. Do not use aerosol cleaners. And do not blow out the grease in the wheel needle bearings as it is essential for break in.

So that brake cleaner idea was retarded on my part.

 

[89 Fox 427]

Lifters are soaking. Valve locks are coming off. Not going to fuck anything up this time.

 

[Steve439]

Check the fit of the valve/locks/retainer carefully.
Different brands can have slightly different angles and sizes.
Put a retainer and locks on a valve; there should be no movement when trying to rock them.

I'm not positive this always holds true, but in my setups the retainer will stay in place with no spring if everything works together.

 

[89 Fox 427]

Well then I'll post this here for you to look at. They sit deeper than the last ones.





The green one came from local machine shop when I fucked mine up. Black is the new comp ones. Silver is the ones that came on the heads. The lock ring is definitely in a different spot

 

[89 Fox 427]

The new ones are about .030 different than what came in the heads. From top of lock to bottom of lock ring

 

[Steve439]

You should definitely check if your installed height is still where you want it.

Other than that I'm not really qualified to say it's OK.
It seems like the stem is up far enough past the retainer.
I think as long as everything's solid you're fine, but hopefully other guys will answer.

FWIW, that will most likely change the installed height of the spring which will change spring pressure & distance to bind.

I can’t tell from the pic but are there spring locators under the springs or do the springs sit right on the head?

It's not right on the head. Not shims, but like a top hat. I have crap measuring equipment, so roughly here...

It changes the installed height from 1.79 to 1.84. I don't know if shims or the offset .050 locks are the answer here.
