To install 3L valves in a 2.5, what is involved..than pulling engine? Is it a difficult job once heads are off? Are upgraded springs/retainers needed or available. Would love a price "estimate" to both do just the valve install (if heads were shipped) and to remove /replace heads (basically do the job in your shop) from Terry or Brad (on or off forum).

Do you think this is a good next step after getting LIM & UIM all port matched out to 35mm or so, big t.body/MAF meter, headers & exhaust, with A/F tuning last? Yeah, this was my thought to do last as a surprise mod for you all, but now the impending CEG collapse has accelerated my question....Thanks
