How much to mill?
How much to mill? I'm trying to figure out how much is a good amount to mill some 243's.
I'm trying to figure out how much would be good while keeping a few things in mind. I want to have the the ability to get a 230/230ish cam in there with no problem. Push rod length is also a consideration. I'd prefer it to be easy to pick the length and not have it end up in between the push rod lenghts (7.4 and 7.375 for example).
I don't know what the base circle of my cam is so if someone could chime in on that, I'd appreciate it. I don't even know what that measurement is. It's the TR 224 I have in there now though.
I'm thinking .015 mill would be good to bring my total "mill" to ~.025 since I'll be using a cometic gasket of .045. Here are my measurements:
stock gasket = .054 - .045 (cometic) = .009
.009 + .015 (mill) = .024
.024 - 7.4 = 7.376 (or close enough to 7.375 that I wouldn't worry about it)
.015 mill good? What do you think?
Thanks guys!

Ok...I think I figured it out. Let me know what you guys think:
stock gasket = .054 - .045 (cometic) = .009
.009 + .021 (mill) = .030
.030 - 7.4 = 7.370
7.370 + .030 (b/c of the smaller base circle of the cam) = 7.400
I guess my answer is a .021 mill?
One other question is, would it be better to have slightly longer or shorter pushrods?
