ok, I got this '69 cougar for 500 bucks and the guy says that its been re-built and not run. So im taking the heads off of it today and they are quench chambers ! IM REAL HAPPY. the heads are peadestal mount rockers and that means I can build a real nice hydraulic motor cheap so im still happy. Ive never seen or knew that ford made a quench/hydro head- whats the deal with that ? what did it come in ? The pistons are flat tops so tomorrow should be fun.

most 4V C heads were pedestal mount only rare cars like the Boss Mustangs and Cougar Eliminators got the adjustable 4Vs, I'm sure there may have been more but most 4V headed Clevelands had the pedestal mounted rockers. AFAIK

But what about the quench heads? Somebody has to know about them.....

 

[tonys10sec306]

any pics?

1970-71 were closed chamber heads. 1972-1973 were open.

The motor I am running now is a 351 4v quench head, running about 11.1:1 compression on pump gas.

Eliminators were in '69 and '70 only. Those that had 351Cs in 70 were pedestal/quench only. Adjustable were Boss351 and CJ heads (71/72). The CJ Cougar was not an Eliminator.

The only clevelands that had adjustable rockers were the R codes: (B0SS 351)-1971, and the HO in 1972. The CJ had pedestals. Tom

HO/CJ==got them backwards !!

Look under the intake ports and post the casting codes - that can help ID the heads. I have a couple pair of closed pedestal heads and a pair-and-a-half of open chamber pedestal. I run the Crane conversion kit on my 2V heads to get adjustable rockers. Works well.

You really run the Crane adjustable rocker kit?
It must be better than I thought then......

 

[Brian M]

I ran the crane conversion kit on my old 351c for several years with no issue.

 

[ckelly]

1500 passes - haven't even seen the parts in 3 years. They must be doing OK in there. Nothing's flown out of the valve covers anyway.

And to think I wasted all of my money on studs and guideplates.....
