Milling Edelbrock heads?

What is the most you can mill big block Edelbrock heads?

We cut .090 off of mine. Not sure how much farther it could have gone.

After the cut the chambers came down to 64.6 cc's.

damn i didnt know you could go that far on them, i cut .050 on mine and havent decided if i want to max out the cam or cut the heads more

I know this may not be the best set up but I was looking to put these on a 71 440 non hp stock piston motor with a 509 cam. Any ideas on how much the heads can be milled before I will get to close on piston to valve clearance? YA A JUNK MOTOR RECIPE.

How far in the hole are the pistons?

I ran a 555 solid lift cam W/ OOTB eddy heads and flat top pistons (no releifs) that were .102 in the hole with no contact.

Last time the heads were off the pistons were quite a bit down would have to check to know for sure. Thanks now I have a idea how much they could be milled just have to do some measuring.

Always happy to help.

Take accurate measurments and let your machinist make the call
