looking for some 181's but no luck.. can anyone help?

 

191's? 181's? 181's are the most restricive delivery valves they have a .054 shoulder on them 191's have a .030 then you get the .024s and .022s and full cuts which got no sholder smaller the shoulder the more the fuel

 

131s are the most restrictive that come in these pumps. 181s are good for 500 horse.

 

i have 181's and i love them

 

i have .024 in my truck and i think it

 

181's have a .080" long shoulder
131's have a .070" long shoulder

 

that should explain more its a picture of 181's 131's and 191' n fullcuts

That pic is not an actual 191, it is a stock 181 cut to a 191.

 

Im curious, what DV do the 215 pumps come with?

 

180 and 215's came with 181dv's
160 and 175 pumps came with 131 dv's
