Milling

[voidfinger]

Ok quick one guys, I'm getting in a set of windsor pi heads to go on my car. its a 98 npi. Sooooo, i'm going to take them to a machine shop to do all the regular stuff, i want to mill them down to make a good flat gasket surface to mate it to the deck, So my question is, will the tentioner bolts still line up or will they be miss aligned and if so, how do i fix it.? what compression will i be looking at, I've heard that when you do the swap you will have 10:1 and i've heard 10.5:1 What is the right number? anyone done this? thanks

i think its like 10.3:1

and i thought you were dropping in a 5.4? ???

i am, but right now i just want some cheap torque power, while i build up my 5.4 . I'm forging one and getting things ready, by then i'll have a daily driver and can put it on the lift and swap and then fab up my turbo kit should be fun. imp:

can anyone answer these questions? thanks

the blot holes should line up fine

and i think the compression will be 10.3 : 1

 

[voidfinger]

so things should line up fine even with the milling?

Yeah. Milling isn't going to change anything. don't worry. O0

depends on how much milling...just a refresh shouldn't do much but some have run into problems with the timing equipment when trying to mill alot and raise compression.
