i bought flat valves for lsvtec setup, how ever i am gonna boost it. i bought flat valves and found out that dished valves is best for boost. now my question is whats the disadvantage of me just tossing in the flat valves?

 

Where'd you hear that? Many of us do flat valves on turbo, and been doing it for years.

 

The difference in compression between dish and flat is so small its not even worth considering. Same with the weight difference.

 

i was just reading on some forums. but the compression makes sense. thanks alot

 

sell them to me for pennies and you can go buy dished
