Probably to cover all the bases. With some of the blocks being blind tapped and others not, if you seal them all you're insured against leaks.

Makes sense to me. Better safe than sorry!

I don't care what engine it is, whether or not they go into water or not...I still use 3M weatherstrip glue (monkey snot). Never had a leak. Also works on rocker studs.

Well, are 351 holes blind too? Because if they are, those heads fit 351's as well, so they're probably just covering all their bases.

OK, I know this is an old thread, but I just ran accross it. I too was a little confused when installing the heads yesterday as to which, if any, of the head bolts went into water jackets. So I put sealer on every bolt. Does anyone see any problem with doing this? (other than a waste of time and material!)

No problem, you should be perfectly fine.

waste of nothing but sealer. The sealer works precisely like the motor oil would have, but is also blocks water from getting into the passages on 5.0 blocks that have the lower head bolt holes threaded all the way into the water jacket like on a chevy small block. The 289's and other blocks didn't do this.

In ANY case, the oil lubricates the threads to ensure proper torque without binding, as does the thread sealer.

if thread sealer works the same as oil , then it could be used on rod and main bolts. next time try it on them and let me know how it worked

Don't go gettin' all huffy... It works the same. All my thread sealer is non hardening, and has the same lubricity if not better containing ptfe, as the oil on the threads.
But I never once said eluded to having used nor recommending to use them on bolts other than the head bolts.... So there!

all early blocks dont have the need for it, but my builder told me just the late model 5.0s need it.

I dont think im gonna put thread sealer and bearings! Just makes them harder to clean!

 

[trashline]

Wow this is an old post Frdnut is finishing up a 289 haha. Now hes got a power packed 408!

i didn' say you recommend sealer for other bolts . not all thread sealer is the same , better to spec the ones to use .

 

[FEandGoingBroke]

Oh, my bad, I misread you. Apologies.

 

[Das Jager]

the lower row of bolts do go into the coolant passages on my 67 block 289, and on my old 66 289 also. the upper bolts though did not.

FYI

Know this is an old thread but thought that I would add some info. My C5AE 6015E 289 block with a build date of December 1966. All block head bolts are blind. Do not go into the water jacket.

 

[FEandGoingBroke]

Cool I reckon
