I’m certainly gonna try that but I’m not gonna get my hopes up

Have you looked on YouTube yet.

No and I also don’t know how easy it is to warp an aluminum head. I know combustion makes a ton of heat but it’s evenly spread out. Whereas I’ll just be torchin one spot.

You will be hard pressed to warp the head. Remember your brazing skills and keep it moving.

You tube.

Looks like she got regular oil changes.

Quick U-tube journey. They are common. There are tricks but most involve a welder and associated tricks with it.

Here is something I have found. If the bolts are flush or just a couple threads recessed use a small carbide burr and very gently knock of the first couple aluminum threads. They tend to be full of carbon from the exhaust leak. Makes the bolts turn and come out easier. Super common problem on Ford 4.6s.

Yep
Well I took the pics but you helped me get them posted up.
I really works well. Many of the guys I work with have started foing it and have svaed themselves some head aches. Seen many guys drill the bolt and put an easy out in and the bolt starts to turn but locks up in thosr carboned threads and next thing you know they are throwing tools moaning & groaning about breaking an easy out off in the bolt.

The son in law is bringing his 71 Buick back to life. We pulled the engine out so he could do the bay. There were a few broken bolts in the manifold from God only knows what. It took some time/effort to get them out.

So I just drop them off at your place? Sounds great!

Watch out for this guy booming chicken....be very very careful.

Lol. Oh come on man, this isn't hard. Just use some finesse, go slow and be smooth.

The heads from my engine are the exact same so they’ll bolt on, assuming of course I don’t break half the bolts off of that one too. Wouldn’t break my heart to get a peak at the cylinders anyway.

Get the valves attended to before you swap heads out. They are miled out. 170+ is a lot of miles. Just get them done and be confident.

I’d rather have the low mileage heads repaired.

Just buy some LS3 heads. #racetruck

This is what I like about INGO; somebody always willing to step up and help you spend your money!

True or just drop the valves in you high milers and lap them back in. Seals and go. If the guides are in spec.


Or.......just get the broken bolts removed from the low milers.....

Iirc the truck heads are the same cathedral LS3 intake ports. So just as good.
