This may be a dumb question but I keep finding mixed answers in searches. My machine shop installed my rocker arm bolts with blue thread lock on my AI 226 heads.. I was thinking they needed thread sealer since they are ported and polished but not sure why? Will they be fine how they are or should I have him remove them and apply sealer?

Also, what's this I keep reading about RTV on intake bolts? Saw that while searching and don't quite understand that.

I am picking up my motor tomorrow so I'm hoping to figure this out beforehand.

Thanks guys!

I use hylomar blue sealant.

Will the loctite hold or will it leak without the sealant?

Blue Loctite is a sealant. I ran with it for a while.

I switched to just the regular Thread Sealant last go around. No issues. Makes removing the bolt a little easier.

If you will look closely at your heads when they port them they open the bolt hole when they remove the hump in the intake runner, thus the need for sealer on the rocker bolts. FWIW

I have been running blue Loctite on my rocker bolts for years without any leakage issues on my AFR heads.

Sounds like the thread sealant may be the best option, but the blue thread also works. This is kind of what i was finding in searches also.. I just wanted to make sure before picking my motor up since he used blue loctite, don't think he understood why i was asking for sealer.

Do i need to apply any RTV to my intake bolts when i install them? That was the only other thing i kept running into while searching, and i've never heard of doing this before. I thought i was good throwing new intake seals on and just bolting the Fast intake on?

I appreciate the input guys!

Nope. No RTV needed. The plunger washer that they use seals them up well. Just don't overtighten them.

And as I said, Blue Loctite is a sealant as well. It works fine. It does take a little more oomph to remove them. So I went to just regular white Thread Sealant the last time. It will keep the bolts from moving as well but won't "lock" them in as tight for removal. I use aftermarket bolts so I didn't want to strip the socket cap on them.

Blue loctite works well and makes very little mess. RTV type sealant is messier to clean up when and if you take it back apart. Bot work well.

Awesome! Thanks for the info guy. I will just roll with it for now. If i run across anything else i may hop back on here and get clarification.

I'll throw a thread together with the build here eventually and hopefully have dyno results sometime in April.

I use Permatex high temp thread sealant on the intake rocker bolts, and always used ARP thread lube on the exhaust side with no problems. Never had a bolt loosen.

What I would not reccomend is ARP thread sealant. It does not like oil and the oil eats through it and starts leaking. Bro built a motor and used it where nessecary and it leaks at all those points. Second time built we used the permatex thread sealant and ne leaks ever popped up.

A BUNCH of the above mentioned blue Loctite. Any reason to think they're BS'ing you?

Teflon sealer. There is no reason to use locktite

^^^ This ^^^

The Loctite/Permatex (same company: can't recall which brand category they assigned this product to) "High-Temperature Automotive Thread Sealer With PTFE". Hanging on a card at your favorite (or even, least favorite) parts store. PTFE stands for polytetrafluoroethylene, which is the chemical name for the substance trademarked by Dupont as Teflon, and therefore they can't use that exact word.
