head work can be a beneficial thing. I would recommend geting it flow tested at each step. If you Do try to go the 3.0L valve install, after you take the head to get the seats cut for the new valves, , THAT is when you would want to do some portig work(make the tansition from cast to machined parts smoother). Also might want to look at mathcing the ports to the intake(I don't rmember which SVT's came with the larger lower intakes... might want to look into that)andworking on the radii of the intake and exhaust ports(not sure the head s on the SVT, but on a regular big block, its lookng at the short turn radius that yields you a big improvement in flow.)
Whatever you do.. BE sure to get some FLOW bench number of before, and dureing each stage so you can see where you gained the flow increase, or where it did not affect it at all... BE SCIENTIFIC, and ALOT more people here will be more.. hmmmm.. understanding.. no...more... no wait.. less likely to give your results a big fat bronx cheer...(right Demon...
) LOL
Good luck!
