Is it worth it? Well, look at it this way Y2KSVT ran a 14.49 without PnPed heads (Fidanza, MSDS, Bassani, stock rims) I have only ran a 14.7 (so far, with the SS UIM/LIM, SS flywheel, PnPed heads (for nitrous), and 17" rims. )


...or you could go with an 01+ full 3L and Not pay one penny for having 3L valves installed...

I heard someone did that and ran a fast ET with high trap speed.

Tom used nearly untouched oval port heads (full 01+ 3L) on his 325/330 budget turbo.
He cleaned up the exhaust ports, unshrouded the valves, and matched the intake ports to the split port. Yes an NA engine would like more work done but it shows the capabilities of the stock oval port head design.


If you are talking about building a 2.5L engine then I would just look at the exhaust valves and exhaust porting. The porting is easily done by yourself.

Any quality machine shop can do the new seats.

The intake side on the 99+ SVT heads is very good to begin with. Just a little port matching at the inlet side to match a RLIM and you are set.
Remember velocity is very important so just hogging out the intake is not the best way to do porting.
Since they are already EH'd this will give you the majority of the gains and is easily done by yourself leaving your only cash outlay for buying exhaust valves and machining the seats & valves. (3 angle & back cut respectively)

2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
