I'll try ARP sealant and report if that worked. I don't think my carburetor will come back on Intake until the end of next week, then I can start the engine again and check the Vacum

Nuernberg, I was right. It looked straight out of the 3rd Reich.

Thanks for the link Ivo .
Was some very interesting stuff about Nuremberg

Silly Me - i thought those structures looked like heavily fortified battle stations.
Possibly anti-aircraft or anti-tank weaponry up top on the unseen side.
.... but they were structures for toilets/bathrooms at an arena.

Zeppelin Field , i am flattered.

The Zeppelin Field (interior area 312 x 285 meters, bigger than 12 soccer fields) and its main grandstand were the only planned structures that were actually completed. It had a capacity of up to 200,000 people.

The "Cathedral of Light" provided spectacular effects when over 150 powerful searchlights projected their beams straight up into the sky.

Grandstands on the other three sides had 34 regularly spaced tower-like structures housing toilet facilities.

The annual Norisring car races – one of Germany's most important motor sports events – are also held here. The Zeppelin Field is a venue for major rock and pop concerts as well.

Yesterday I checked all Studs on Intake, and 6 of 8 were drilled through. I am very disappointed with the quality of Edelbrock. OK, I know that is not German quality but something like that cannot happen and no, heads are not ported, so they came from Butler.
Maybe it was better to buy Kaufmann Heads.
I have sealed all intake studs with ARP and checked them with pressure, I can no longer find any leak. Engine will be running again at the end of next week that I first want to relocate my cables.

It is a long standing issue on those heads. (rocker stud holes)
They should put a warning paper in with each head.
Admitting the technicality openly must be more than they care to burden themselves.

If every sales ad openly stated the issue, they would lose another good percentage of sales amongst general users - to Kauffman and SpeedMaster.
Supplying a printed notice with each head should be a minimum act of courtesy.

They are good heads beyond that issue.

I thought it WAS part of the instruction sheet that came with the heads. At least I believe mine did. That may be 15 years ago now...

I just checked the instructions with the last set of CNC chamber heads I got and there is nothing about sealing the rocker studs. It's not a big deal to me, seal them using your favorite method and never have a problem.
