Interesting
Here’s the link for Stans

You have to kinda go between Keith Craft and Bill Ballingers info but it shows reversion and yours and others did not.

Looks like they all kept going up, which is what you want.   You won't be able to see reversion/turbulence, it has to be heard on the bench.  You know it when you hear it.

Crap you’re right. I transposed one line onto another.

Have the heads at Valley Head service being repaired.
I took the short block to QMP for an extensive checkup. Full pressure, mag, sonic and baking.
I’m scared about the water jackets. They’ve been sitting for a long time and actually developed a cap on the crud that was inside.
Be a couple weeks at least.

Marc -

I'd love to see how the head weld repairs turn out, and how much it lightened your pocket.  I have a cammer head with a cracked rocker shaft pedestal that could use some love...

I bet your block water jackets are fine.  It's not like they've been sitting years with salt water in them.
A careful study of failure will yield the ingredients for success.

Thank you for those good vibes.
I’ll take some good pics and fill you in on money spent. Turns out that once it got cleaned it was apparent that it needed 4 or 5 helicoils on the exhaust side of the bad head also.
Cross fingers that’s the worst of it.

A question for you smart people.
Just a question I’m rolling around in my head.
Porting CJ heads. Obviously I don’t have any “leave as stock obligations” with these N heads.
I’m thinking bang for the buck here. Is porting worth it? I’ve read maybe just exhaust porting is a good deal but that’s just reading on the net and not word of mouth from the guys that do it for real.
What makes sense? Porting is not cheap and I’m probably going to have just over a grand into the restoration and valve job. However I would like to gather all the ponies I can reasonably. BTW it has what I think are the original valves in it (Bump on the intakes) and it looks like they can take another valve job fairly easily.
I realize one guys reasonable spending is not another guys but me not being familiar with N heads leads me to throw the question out there.
Thanks

Porting will up the horsepower at least 30 if done right.  The intake manifold needs to have some work on it if the heads get ported.  Some of the replacement valves have the bump in the intake valve just like the Ford valves.  I just broke down a pair of CJ heads yesterday with off brand intake valves in one head but they looked like the factory valves in the other head.  Changing the valves to 11/32 stems, going oversize to 2.100, or 2.125 with 45* seat will help with improving flow without shrouding them.  Hardened exhaust seats and 1.680" exhaust valves at the minimum.  As you can see, the price just keeps going up, and that is why most folks just go TFS or BBM or Edelbrock.  Joe-JDC

Thank you Mr. Craine.
I know it’s simpler to go with new heads and I have before. I just have a love affaire with the older stuff. I’d like to have a nice running real CJ with as many original parts as makes sense.

I would pick a horsepower goal and then see what you have to do to meet that goal.

Those heads with just a valve job and good valves would support 450-ish hp with a streetable setup.

No issues then.  I've got two 428 CJ builds in the dyno section that made that much with no port work or any exotic parts.

Well we have issues.
First though the repair is finished and looks just fine. Timeserts were installed in 4 bad bolt holes plus the ear repair.
Mr. Conley the weld up repair and the timesert is about 170/180 bucks. Less than I expected. 45 minutes on the welding plus the timesert prep/install.





The issues are that the guys at the shop don’t want to put hardened seats in because there is almost no backing head material under parts of the seats. As well as the seat depths are all over the place.
As we talked about what makes sense, the idea was floated to run solid lifters with the seats that are already installed as that may ease the hot spot pressure on them.
Hope these pics make sense to you. Putting a finger under the seat there is just nothing there. I asked about welding some more material in there and they didn’t like that idea both cost wise and the weld would be harder than the head material causing more problems.
Anyway, here are the pics of that.







So it all comes down to how much do I want to save this CJ. I know, I know, aluminum heads would solve all my problems but that isn’t the point here. Although I’m starting to question my sanity.
I’m figuring I could leave these seats in and drive it sparingly. It certainly will never be a set of race‘heavy duty heads and I’m starting to revise my hp desires.
Wuch y’all think?

IMO, new hardened seats are not critical.

Agree with Brent.  If you were pulling trailers up the Grapevine every day for ten years, you'd see an issue.  For the load and amount of use that engine will see, it will last longer than you.

Thumbs up on the repair!  I'm going to have to make a little stop up there!  Mine will be more expensive because the SOHC head will probably need a line bore after welding the rocker shaft support...

Thanks for the update Marc!
