What camshaft and intake do you have in mind ?
I would look at the Dart Iron Eagle S/S heads.
Comp. Products had them bare for $460.
Assembled where $625.
I would look at cams that are at 230@.050 on the intake side and 236 to 240 on the exhaust side more for the N20.
To run a cam this size you will need to have a 9.5 to 10 to 1 comp. ratio.
I would go 108 -110 L/S or 112-114 L/S if you want to use the spray.
