Upgrades coming, plug question

[JeffW]

I'm about to install several significant upgrades. I'm trying to decide if I should run a CR42TS or CR43TS. I'm currently running a 43.

Here are the upcoming mods:

Hi Flow ported heads from Nick Micale
T&D 1.6 roller rockers (and taller valve covers)
206/206 hydraulic comp cam w/ lifters
RJC Power Plate
New double roller timing chain/gear
The 60# injectors from Mike Licht
Extender chip for injectors, 96 oct, 21/19 timing
6.2 eprom to upgrade translator from 4.1 version

I'm leaning towards the CR42TS plugs. I do want to stick with the AC/Delco plugs.

Oh, and the eternal question. With these mods, and the other parts in my sig (that aren't being replaced), any estimates on 1/4 mile times. I realize my restriction is now my turbo.

You could go with the 42s if they foul out easy, go to 43s. With your combo, Id go 43s.

Flip a coin. Better yet, run NGK's...

...Also, replace the plugs with AC R43TS plugs gapped at 0.035" for 13 to 14 second cars and AC R42TS plugs gapped for 0.035" for 12 second and faster cars. For specific hints and part numbers...
