just wondering if these are supertech valves





they look stock to me

 

intake looks like a maybe...exhaust definitely are not.

 

no supertech val. are flat..... does or stock or onmi...

 

supertech does make a dished valve though. Any more responses before i buy this head?

 

the intake valves are aftermarket.......unfortunatly there is no way of telling who makes them. there are at least 4-5 different manufactures who sell black dished valves.....and at first glance they all look the same.

those exhaust valves look stock.

 

Sorry to bump such an old thread. Can anyone confirm that these are supertech valves? Do supertech exhaust valves have the letter "f" on them?

 

holy 8 year bumped thread batman

from what ive seen, lots of stock valves say F on them....
