I'm not sure why you'd do either? Sounds like a street/daily driver? The issue is the lack of valve reliefs(not a problem for your situation). Put a thin head gasket on it(if you want a bit more comp)and go. The stock pistons are approx .050" in the hole,no big deal.

LOL I got that. Id guess as a 40yr veteran mopar racer I'd ask where are the important gains in any build? "quench" is waaay down the list,but on this site its just like gold(lol),not close and Id gladly give a point of comp for the better ring pack of the factory piston all day. We have made over 600hp on the factory junk short block,yep it only made it 6yrs but it had no quench.lol Some folks would trip over a nickel and miss a quarter.

My 318 magnum I went from the factory .086 quench distance to .038 made it ping a lot less as well as better MPG TQ and HP. That was the only change at that time, I even took it to LA and pulled a car up those big hills on my open trailer at sea leval and no pinging on 87 octane california crap gas. After that experiment I am a big fan of maximizing quench area and minimizing quench distance. My goal with this 2000 360 Magnum i just bought is .030" quench. Might take some decking... but i paid very little for the engine, so i think its worth an experiment. I kinda wanted to go with the 318... seemed a better choice for less machining, more tolerance, better piston shape... many details... but i just got such a sick deal on this 360 i couldn't pass it up. 360view... i think you'd just be better off with the machining. Thats a lot of thickness to ask from coatings and such... and (it would seem to me at least) a little hokey.

You got good quench/went from 9-1 to 10-1 & more power/no pinging on 87/no other changes. that is incredible! what a success. Makes a believer out of me.

We're not talking numbers 340's here... screw one up, you're out a couple hundred bucks and the machining.

David Vizard on SBC V8 test rigs wrote that he saw no increase in horsepower once quench was 0.060 inches.
Wonderful, did he happen to look at detonation suppression? Dave also seems to be in the minority since most data I've seen pretty much says at .060" you aren't getting any quench effect at all.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Thinnest gaskets are Mr. Gasket 1121G. 0.027" - 0.028"
Everything else is thicker.
MP sells a similar (maybe the same) gasket. Check prices as the Mr Gaskets come one in a package so you have to buy two. At one point I got the idea the MPs were two to a package, but they're not always available.
Dave, totally closing both intake and exhaust valves turns the cylinder into a big air spring. Since nothing is being pumped, no work is done. There are losses though, first is friction and second is, some of the heat of compression has to leak out into the cooling system. There is also something called hysteresis which means that some of the energy required to compress the spring isn't regained when the spring is unloaded. I think this component is negligible.
When one starts looking at articles in the Journals of the Society of Automotive Engineers, it becomes clear that EGR is very common, but since the advent of variable valve timing, it is easier to get EGR by adjusting the exhaust opening and closing events. The final product engine is the result of probably thousands of runs of computational fluid dynamics, dyno tests, and actual street driving.
The computer is programmed to give the engine the best combination of air, fuel, spark, etc. which will still be working well enough to pass an emissions test after 100K miles. Tuners are able to gain power or efficiency by reducing the safety margins.

R. Thats disappointing. There is no .020" steel shim gasket? If it matters, both surfaces, deck and heads will be freshly machined. If i have to use a .027" gasket i'll have to lop .045" off the deck... That seems excessive...

I have a pair of MP steel shim SB gaskets. 0.0215" email if these will work for you.

They have been out of production for a looooong time. Subject comes up here about annually.

I deleted 33 but evidently that ain't enough. I will get in there & do a bunch. at the top I am seein: "quota" in red which obviously means I'm over the limit & it just turned red recently then there is: 1028/500. how many do I need to elim to resolve this?

My email address is correct but it might have went to spam but I do not know how to check/correct that. PM's have been coming thru so you might try again (I did not yet delete any more PM"s so not sure whats going on there). I will send you a PM right now.
