To Quench or Not to Quench?

Why not get with Doug Dutra and see if he has or knows where another Argentine closed chamber head is? I say go with quench if you can, sure, but to get a stock slant head to be quench I think would be a costly proposition. Gettin into some of that "exotic" you talked about. The stock heads are just not made for it.

I don't think it would be difficult at all.

Compare these PIX.

The 1st is of a \6 head that has had a severe head deck reduction.

Now. compare the stock late model combustion chamber.

Rather than going the 1st route, which would, IMO render a severely thinned head deck, doing a moderate .110" deck reduction on the stock head followed by a 3.500" perimeter cut (required to allow the + deck piston) could be used to make a uniform quench pad around the combustion chamber.

I don't think we are getting into anthing that the average (competant) automotive machine shop could not accomplish.

Not what I consider "exotic".

Out of the box perhaps, but nothing extraordinary.
