4.6L engine should last up to 200K+ miles with normal
driving.I don't see why your engine shouldn't last you
if you don't go pounding it everywhere.If you do the
headswap now you can always do the bottom end rebuild
later.Take care of your car now and it should last you till later.
You can do Stage 2 port and polished heads from VT,Stage 2 VT cams,
headers,and a great tune that would be a great combo.
What do you want to do with your car? What brands of PI heads are
you looking at? www.vtengines.com Also Congrats!

Living in CA you should keep the 6 catted h pipe and don't do long tubes.
If you get caught with anything different than the stock H pipe
or long tubes you could get your car impounded,1K fine,or depending
on the cop a few nights in jail.I belive the Stage 2 VT heads aren't the
problem it's the stage 2 VT cams that will hurt you when it comes to
emissions.You can always go with the VT stage 1 cams and make great
numbers and still pass emissions.Just look for a good place to get your
emission testing done every year and a half.You can go with the BBK or
FRPP shorty headers they will get you good results with the PI Headswap.
Good luck.

With the increase in air flow and with the stage 2 VT PI heads
you will probaly be around 290-300 rwhp so,you will max out
your fuel injectors and have to upgrade to 24 lbs. fuel injectors
to have enough fuel.With the non-pi set up you are most liking
around 190-200 rwhp.I think you will gain 100 rwhp with the
stage 2 VT heads and cams.Thats some great numbers from stock
if you ask me.
