is shaving your head the same as when poeple say milled head??

 

yep

 

is there different mills, you know like bores???

 

Not quite sure what you mean bud?

 

just FYI 30-40k is the most you can go with the H22 head personally I wouldn't go past 30k. I would rather use a thinner head gasket then milling my head again... can't go back...

 

so if you mill .30 can you still use a thin head gasket, how much you think that will bump your compression

Have the machine shop cc your chambers and you'll be able to figure out your compression better. Without knowing this, we'd just be guessing.

Shaving your head is something done by your barber, milling your head is done by your machinist

 

hahah, good one

 

What kind of head gasket should you use after you mill your head .030??? using a thinner head gasket after milling your head give you even higher CR???

Are you running stock cams?

If you milled the head AND want a thinner head gasket i would at most run 2 layers instead of 3 but then again i would still have the motor clayed for proper clearances.

Is this head going on the block in your other post with the 11.5: 1 pistons? have to be careful man- while you are raising your compression with thinner head gaskets and milling the head you are also bringing the dome of the piston closer to the valves. Might be cutting it too close

 

im still not sure what cams should i buy between the Blox Type C or the Crower stage 3??? so would a 2 layer be good, an would it raise my compression a little even after i milled my head .030 and after the 11.5:1 CR pistons??

 

well if you already milled the head and have higher comp pistons , and are getting larger lobe cams then I would leave the stock head gasket. Thats just my opinion.

Is a .1-.2 bump in compression worth the extra amount of safety? Not in my eyes but to each his own bro.

FWIW I dont even have a milled head and when I put my new head on I am still sticking with a stock headgasket because of my cam choice.

What cams you suggest with my build??? so just buying a OEM head gasket would be the best choice

 

im running a h22 with a .030 milled head
i am runnig skunk stage 2 cams
this is also on usdm pistons

Head milling and different thickness headgaskets allow you to custom taylor where you want your compression level to be after pistons. You NEED to determine what that level should be by figuring out what cams you're going to run, the type of header and intake manifold you're using, the type of tuning you're going to use, what kind of access you have to a decent tuner and dyno and what your overall power goals and vehicle usage will be.

This is why people on the internet can't just simply tell you what to do, it varies for everyone. If you don't know the answers to the questions I asked, you need to do some reading and searching and looking at other SUCCESSFUL peoples builds to give you some direction. Once you have a plan you'll know what you need and where to go and what to buy. Just think about this for a minute...you're trying to build a house and you don't even know what the final layout will be before you start trying to lay the foundation.... if you fail to plan, you only plan to fail.

 

 

A couple of my h22 head had .070 before it reached the cutoff service dimple.
It all depends on your goals.
.030 off the head is 1 point added to your compression on a standard h22 87mm bore block

 

are you sure .030 shaved off a h22 head is 1 point in compression
i was beliving it would be about .5 or slightly less....
but if it is a full point im felling better about my cam choice on stock pistions

 

if your head was shaved .5

so .070 is the max you can shave an h22 head, is this what you mean by the "cutoff service dimple"?? So .030 would be 11.6CR from stock CR wich is 10.6CR? correct me if im wrong

Hows your clearance??

i was using a h23 crank and stock cams so i had no problems....but i ran the headgasket alittle thicker

 

you know the clearance for head milled .040 and crower stage 3s or blox B cams?
