My friend kinda got me scared about milling a head saying that it's hard to get it even. Is there any truth to that? Thanks

 

A competent shop can do it. The only CON to a milled head is the once it is removed it cannot be replaced.

 

bad thing would be timing belt will loose...depending on how much u mill......might have to fly cut the pistons....

 

Yep once milled can't go back..

 

Do it only if the head is out of square is my take on it.

I don't remember the max that you can mill, but I know there's a limit for what'll keep you from having tensioning problems, and keep the cam timing pretty similar to before.

 

I had my head milled and now I'm going to put on the Mugen head gasket.. should throw me up to 11:1-11.5:1 compression on stock B16 pistons...

 

well the thing is i already have 11:1 compression but i want the nice 12-12.5 compression. So i imed Topspeed and they said all i needed with 15 thousandths. so i may do it since it's not that much and i don't wnat to rebuild the motor just yet. thanks

i learned from the master ...dill weed

 

lol,
like the title says

poison -- who wonders who this 'master' is

 

Why are you bothering me???? go back to your 14 wives

 

haha i guess that's what UT is about, at least there is 14 wives to move around in this state, there isn't enough room in CT for 14 wives....now at least i can pick up 14 wives now can't i?

as far as the topic goes -- miling the head, already talked to u about that on the phone

 

Pretty soon you'll be called Grandpa Brandon...how cute

 

lol, no, Da Piemp Brandon. and you? i don't think u can have grand children giving head lol j/k bro

 

so which one is it tonight....Amanda-lynn-Betty-Bob, Peggy-Ann-Rupaul or the other 12 she males?

 

LOL good one

i believe they use a lathe... its a machine so the accuracy should be perfect...

slight problem with milling is that if you ever want to increase piston dome height you might run into problems..... alot of people mill the hell out of their head and are stuck with lower lift cams ...

.015 doesnt seem like too much of a mill..... isnt .005 resurfacing?

 

Topspeed? lol

 

Um, no... guess what machine they do use.... A MILL. LOL.

 

How are they going to use a lathe to MILL a head? It would be a pretty cool sight to see a cylinder head spinning on a lathe. Not trying to flame just speaking my mind.

As for the loose timing belt issue...you would have to mill A LOT off of a head to not allow the tensioner to take off the slack.

The maximum amount of material that can be taken off of a DOHC VTEC B-series head is 0.040" per the Helms manual. From my experience milling the head within factory specs will not affect the ability of the timing belt tensioner to do its job.

Is there something wrong with Topspeed? Are there any machine shops that you guys reccommend?

 

no cons except you cant go more than 30 thou on a gsr and 40 thou on a b16a. Get any v8 shop to do it, also hav ethem clean it properly too.

to achieve more compression, mill 15 thou and use a thinner headgasket, incase anyone ever messes your head up by retorquing/untorquing in wrong sequency for examply, and warping head you have room to play with. as a guid look at the marks on the head which shows the max milling possible.
