Re: Milling heads



When I replaced the head gaskets on my 273 from the factory steel shim (.022) to Fel-Pro Blues @ (.040), I had to push the intake down pretty hard and take my time installing the intake bolts as they were getting out of line pretty good.

Keep in mind head gaskets can be as much as 50 thousandths thick as compared to the factory shim steel being 19 thick

Thanks Dodger, I am really bad with thousandths.  I had heard that
intake side of head should be milled  2/3 of what the deck side of the
head is milled.  Is that comparable with your formula ?

And what 65 Darwin says--That is an issue I had not thought of . Even
tho the intake surfaces are at the correct angle, will it mis align
the bolt holes and port match????  I can't quite get my foggy brain
around that.

Don D. said with stock 1978 passrmger car 440 heads (8.2 C.R. ?)  that
60 thou. milling would wake that engine up. What he did not say was
what the comp ratio would be or what else would need to be done to
make it all fit together correctly.  I am kinda thinking about a 30-40
thous. milling.

Any other input is welcome.....Thamks....................MO

Mo,,,,,,, if memory serves,,,, this is the correct formula, am sure that the machine shop that does the milling will know for sure, and as I recall
you can go up to  about .060 before causing push rod problems

mill the intake surface of the head 0.0095 inches for every 0.010 you take
from the deck/head surface.
