About 600 miles ago, I heard a loud exhaust leak, all of the sudden.
After inspecting it, a chunk of the head at the left rear exhaust port fell off somewhere in TN. I think it had a leak there to begin with.Since I have been piling on the epoxy...But every 200 miles or so, It will burn off, and burn the plug wire off.

I am trying to get to Phoenix..where I or I can have a shop repair it...

Been doing some searching this morning too...

So ..
1. Does anyone know of any quick fixes?
2. Later, Can the head be repaire by filling with weld...and installing headers?
3. What is invloved with head replacement? Can you get the head off where the engine sits?

I have a f53 w/ 460 . 1995 holiday rambler.

Thank you

I took both heads off and had 5 ex. studs dried out and heads repaid Put new ex. seals on before putting heads back on.

Yea, I think I read some of your post...

You where able to remove the heads with the engine still in the rv ?

So, does anyone know if the heads can be removed with the engine in the rv?

rockready, Yes the heads can be removed with engine in place.

I'd think getting the heads off wouldn't be a problem. Mines a V10, and there should looks like there's plenty of room.
I don't envy the man who's gonna lift that iron head out through the wheelwell though.

It's not gonna be worth it to try to fix a broken iron 460 head. Replace it.
I think Edelbrock might make an alluminum hiperf head, here's a link Edelbrock.com - Cylinder Head - Ford - Big Block - Performer RPM 460 it says 67 to 87, might be worth a phone call for fitment though. I bet a pair of those and a matching manifold would add 150hp to that 460!

Heck, you could drop an oil can thru those intake ports, arrrrg arrrg arrrg!!!

Thanks... I was hoping they come out the top...

Alum heads? I'd just be happy with a dependable rig... 27k on this RV and I have to replace heads...Jeez...

Thanks though, but dropping 5k on a 15k rig, isn't me.

Stock would be fine..

I'm still not convinced a good welder couldn't fix this...Weld the manifold to the head for all I care...

The 460 has been known for breaking head bolts as well as some of the heads cracking.
Heat expansion of the heads causes this to break the studs. The heads can be replaced without removing the engine.
