how much is it gonna cost me to get the heads milled on this lt1 engine? any1 have any rough estimates

 

when you say milled do you mean decked for flatness? if so i payed $50 for the last set i had done. If you mean ported and polished it is several hundred depending on what you have done. When you start having bigger valves put in it gets pretty costly. I had a set priced for 2.02" I and 1.60" E valves and ported and polished for $800. All depends what you want and where you have them done.
