I have a 2004 lq4 and plan on buying prc stage 1 ls6 heads. I'm figuring the compression ratio should be about 10:1. If i use the 243 castings which are 64 cc how much can I mill them and still use the ms4 cam. I'm asking because i want to get thecompression ratio around 11:1 but want big cam and cant afford to flycut pistons. So can i mill them to 60 cc and ms4 still fit? I would like a texas speed rep to comment because of work schedule i havent been able to call them.

You won't be able to mill them without flycutting.
