I have a set of 167 and 193 delivery valves, how do these compare to 181 or 191 delivery valves? ive got full cuts and im looking for some less smoke (i know, whats wrong with me?! haha) and since i had these maybe they would work.

I've got a set of 167's and they look like a 131 but without measuring them I cant say how close they are.
 
well from all the measurements i took from them, 181's and the 167's were almost identical, so i put the 167's in. compared to my laser cuts, the idle is sooo much smoother, starts quicker, able to adjust idle better, havent driven it in the daytime yet to see smoke, but from just revving it in the garage it seems to smoke worse!? not sure about EGTs cuz my thermocouple died :poke:. it does seem a touch slower, not sure tho.
