Another 318 build, and questions. (LONG)

many thanks, im really digging this input!!! ok so i did some serious reading up on quench (sometime when abodybomber posted about it, thanks haha) and dynamic compression ratio to determine the required octane. My current heads average 74cc chamber volume un-milled but can be as high as 77....i WILL cc out my heads when i rip this monster apart. So thats what im running with for spec's sake, and a fel-pro head gasket 4.18 bore and .039 compressed, and XE268's intake spec, closes 60 degrees after bottom dead center, and zero-decked, @3000ft above sea level. with the KB399's my dynamic compression is 7.37:1 and static is approx. 9.7:1, with KB167's dynamic is 6.36:1 and static is approx 8.45:1.

seems to be and general majority here are against domes, thats great, now my main brainfart is, how do i "build" quench into this thing with my existing heads? Does anyone know if these things can be milled a reasonable distance to move the cast-in "quench pad" within .040" without some fancy razoo head gasket? or is this a lost cause? If it is a lost cause, any ideas what i can expect for downfalls or issues? if any? And zero decking would be useless at that point, right?

Second question, since im running the largest chambered 360 heads, i can have them milled .040" to remove approx 8cc's, or .050" to remove 10cc's, removing 8cc would take the static to approx 8.9:1 or 9.19:1 (depending on what my heads CC out at)

Removing .050" would take it anywhere from 9.09:1 or 9.4:1 static and 6.88:1 or 7.13:1 dynamic.Ill be running hydraulic lifters for simplicitys sake, and if i do have the heads milled that much, any recommendations on kickass do-it-yourself pushrod kits?
