Hi,

What are the specs for the valves on a 2.7 conversion? Standard cam. I just found a note from the guy who built it saying .10mm intake & .15mm exhaust. Are these correct as I know standard is .25mm?

Thanks

unless you have an aftermarket cam that says otherwise use stock numbers maybe slightly looser will smoothen things out
