i have a set of eddy heads decked fro 88cc to 64cc.any one know how much to cut the intake. thanks

How much was taken off to reduce the chamber volume by 24 cc? BTW, that sounds like a LOT of milling to me.

When I have my SB Eddy heads shaved, I wish I would have had someone mill the intake side as well.. Everytime I want to put a new intake on there.. I have to remember the cost to have it milled..

To my thinking you would need to know what the stock height outer bolt bosses on the Eddys are; they might be 1.00" like stock Mopar heads.

Then measure your heads to find what was cut, for example .090" and multiply by 1.23 X .090"=.1107". Or, another way 9 [.090 ÷ .010] X .0123"=.1107" off the intake.

Typically its about .005-.006 per cc.

I usually take a minimum of 1:1 of intake per deck milling, and I think 64 Post is correct at around .011/.012 is usually the real number off the intake.So .010 off the deck, .011-.012 off the intake. Thats a lot of cutting on those heads. How come?

The 440 I have been testing with lately has Eddy's cut to 65cc's.Besides cutting the intake mounting flanges to get it lined up,I also had to make a cut off of it where the bottom of the flange meets the valley tray.Valley tray fitment is an issue as well,the heads dont butt up to the edge of the block like they should when the heads are cut this far.
I hope it goes better for you than it did for me,but it is what I had to work with on this build.

For every .010 off of the deck surface you need to remove .0123 off of the intake surface, but before you go crazy on the head I would probably look at the intake, because if you start milling the intake surface of the head, you going to end up with a head with very little valve cover rail. click on the link for milling info http://www.mopar1.us/mill.html

when I cut my eddies down to 75cc, i hade the intake milled and welded a aluminum plate to the bottom of the intake. The valley pan would not even come close to fitting.
