im @ .110 off the head and .030 off the block...
i wouldn't really go any further (.110) when you can mill the block the same amount...
I have seen as much as .150 come off of a factory head. I personally think take what you can off the Block as this keeps the head CCs up for use with power adders or different requirements from the engine. The block is the most likely to have a unrepairable problem. Also a well ported , large valve head is NOT cheap.What is the maximum amount of slant 6 head milling anyone here has done successfully? Seems .100" is common, but I've heard of .140" and beyond. What have you done?
X2 moparKid :happy10: I am just learning this myself and seen your build =P~
You will be spanking some V8 with your /6 monster :cheers:

P.S. wouldn't decking the head a ridiculous amount eventually give you a close "kidney" shape combustion chamber, which is good...
If the head could be milled that much.... IDK myself.
While the shape is good, actual amount of swirl is another story. Getting swir from the air and fuel is more than chamber shape.
I think you refur to this.
Also, the smalle cc amount to raise the comprsion is good, theres also no quench taking place. The smaller head cc amount (The heart shape now present) would be preety good (Or should be) with a zero deck piston or a domed one fitted to the cylinder heads chamber.
Oh course, this could put pump gas out of the equation. E-85? IDK, actual ratio would be of concern.
So you just look at the pictures of the Argentine Head.

So .150" has been done without problems?
