I m gonna have a brand new blueprinted shortblock going into my TT and along with that I was thinking of getting a new head. I m pretty much going in for a new stock head with new valves, springs, HKS cams etc. I ve been looking at the Brian Crower valves, springs and retainers. However, it seems that a complete set of BC in/ex valves (only) costs 410$ as opposed to the stock Toyota valves which cost about 600$. Could this have anything to do with quality at all??? Which would you ll recommend???
Furthermore, I ve been told to go in for shimless buckets instead of shimmed buckets. Does it make a considerable difference???
Cheers
