for 185 i'd take them off, port them, and put them back on. that's alot of money just for porting tgv's. it's not rocket science. kyle do it yourself, if you take your time and are careful you can't mess it up.

REPLACE YOUR GASKETS! do you really want to have to take you manifold off a second time because it's leaking and you cheaped out. not only that but they will more than likely tear when you take the manifold off.
