To Quench or Not to Quench?

I get what you're sayin. And when you posted the pics, I can certainly see where you may be able to get quench......but I'm tellin you, between the two heads you have pictured, the one that's not been milled is the best.

I agree 100% The excessively milled head is nothing more than an unwieldy boat anchor IMO.


The reason the later head is better has something to do with the filled in area under the plug. It gives sorta a "swirl" effect. At least that's my understanding. I'm interested to see what you come up with. I think anything would be an improvement over stock.

The "filled in area uder the plug" as well as the flat spot on the opposite side are the reason that I think that by counterboring the deck to reach these area W/a 3.510" diameter recess will achieve what I am looking for. By bringing the piston crown closer to that "filled in area" I will increase the "swirl" affect. That is what quench is all about.

The only thing different about all this is that it will rely on the piston coming out of the block by a bit more than what is usual. I will have to make sure that the ring gap is ample on the top ring as it will be coming awfully close to the top of the bore & the resutant hot combustion gases. All of this "quench" will be occuring quite some distance above either the block or head deck.

The same thing could be accomplished by filling in the area W/weld before the deck is milled. That might technically be the better route, but it would be expensive.



Oh and just so you know, you and your slant buildin woke me up. I went out in the shop and disassembled my bwoowack rockers yesterday and put them in the cleaner. I'm gonna call Gary myself and see what I can work out. Thanks. lol

For the life of me I could not understand why you hadn't already done that.:scratch:
