Thread sealant

1 Attachment(s)
I am about to replace the original cast iron heads on an 8ba V8. I have a question regarding which thread sealant to use. I have both of the pictured products on hand. I also have read some of the prior posts on thread sealants. I am not necessarily asking which is the superior product, I am only inquiring whether both are satisfactory for this use. Thanks for any input.

Re: Thread sealant

I have primarily used the #2 non-hardening the other has teflon in it but either one will be satisfactory.

Re: Thread sealant

Along with applying to the bolts I also smear the threads in the block as much of the sealant from the bolts will be left on top of the block when you screw them in.

This works great also for head bolt and studs threads.

Re: Thread sealant

I use the pipe thread sealant in all my builds. Probably 30 - 40 engines with no problems.

Re: Thread sealant

Me, I'd use the thread sealant with PTFE. Also, put a good amount of anti-seize on the sides of the bolts and a little bit of moly-lube/grease under the heads to help with more accurate torque readings.

Also, no matter which sealer you use - let the engine sit for at least a day before you fire it up . . . helps stuff harden a bit.
