Building Motor some questions....

[P at]

Looking for opinions and advice on this one.  Heres the scoop....building
the motor for the 91 P10 race car, high port, and gettting down to the nitty
gritty...

Bottom end:
Eagle rods
300ZX NA pistons 87mm
Cometic metal head gasket.

Top end:
S5 cams
Custom Exhaust maifold
Rocker arm stoppers
Slight port and polish

So, some questions I have, since Ill have the ECU sent out to accomodate the
S5's idle issues.  I was wondering if I should shave the domes on the
pistons to get a lower cr

...OR...

Leave the domes intact to achieve an even higher cr, but I am not positive
if the valves will clear running the high lift of the S5 cams, and may have
to cut the valve reliefs deeper on the poston to accomodate this.  I also
understand that Ill need to run the 11:1 program on the ecu if I keep the
domes on the pistons.

Ill be sending the block out for the over bore with a torque plate and might
get the pistons coated as well, just trying to do this on somewhat of a
budget.

Thanks for the advice,
P@
