is there a difference in the size of the valves in a b18 vtech head vs a b18 ls head? because i have a b18 with vtech head i'm trying to swap all the parts besides for the cams to the ls head. ( i have an ls block) and i'm without a car until i find out.

 

They have different part numbers. The length is probably different.

Have you considered an LS/VTEC engine since you have most of the parts? Look at the Integra FAQ for some informative links.

 

ok would you be able to tell me where i could buy name brand ls valves tho?

 

For the VTEC or non-VTEC head?

I know for the VTEC that Ferrea and Skunk2 make valves. I have no opinion on these.
