I just got my bigger dv's today and on the top of them in the center of the cross theres a little hole on all of them except for one? Is that normal?

 

Anybody know?

 

can you tqake a pic? is it just the center they use for turning???

 

Yeah, see how all of them except the one with the toothpick underneath have pits in the center

 

pull the valve out of the holder and compare it to the others, and take us a pic if you don't mind. they may have just used another valve to make the set. but the mark on the bottom does not really matter. the relief cuts are what give you the extra fueling. make sure the area under the valve seat all looks the same on the valves. who's dv's are those?

 

Can I email you the pics? I made them too large to be uploaded but wanted to show you them in detail.

 

Heres some clear pics (courtesy of 12valves recommendation)

 

that looks like a stock 181 valve to me. what # is stamped on the top????

 

nice!...........

 

Theyre all marked 131 except the one without the hole on the bottom, its a 181. They're supposed to be laser cut....

 

To me they almost look like in between a 181 and a 191. Not for sure though. Where did u get the DVs?

 

ok ive never seen a 181, nor a 191, Josh, do you mind sharing pictures of each? or do you have em in the truck?

BTW

 

Can anyone post a pic of a 181 or 191 so I can compare them?

 

I dont have any pics but the one in the middle looks about like the 191s i put in my truck.

 

anyone ever hear of a 167 d/v?
