215 pumps have 181's just like the 180hp pumps. and yes there is a considerable difference between 181's and 191's. i believe the HP difference is mainly injector size between the 180 and 215 engines however the 215 pumps are slightly different.

Are the 7mm dv's bigger than the 191's, .024, and .022's?

 

Per Weston:
024 ~ +50cc's
191 ~ +60cc's
022 ~ +90cc's
7mm ~ +100cc's
Full Cut ~ +140cc's
We've been using 7mm valves in multiple trucks for about 2 years. They seem to be very well rounded. No heavy smoke increase or egt increases unless your standing on it. Pump tuned correctly these dv's will out do any other combo imo.

Do you think they would be good for the stuff in my sig? How much do the 7mm cost?

 

$250 for 7mm
