ok i a going to be sending my heads out to lloyd to be ported.
as of right now i am going to run stock size valves. Is there going to be much power diffrence. Or should i pay the extra cost for bigger valves.

but will stay stock if possable.

still want to see around 400rwhp

 

Get the bigger valves it helps everywhere on the flow chart. Ya just need the 2.0 intakes I think the ex. stay the same size.Check with LE. If ya are going to get new valve get .100 longer I & E your spring selection is better and ya can run more lift without the headaches.
