im looking at running a tsp t2 cam. and a set of ls6 heads i havent decided wether i want cnc'd or stock ones. but my question is this i would like to run 11.4:1 or around there to make a bit more tq. would i be looking at flycutting the pistons if i ran the tsp t2 cam?

also with milling the heads you need to get shorter pushrods correct?
