It can be done but it wont be cheap…you will have to make up an actual jig and send it to a known gasket maker(cosmetic,felpro,etc) with ur EXACT specs I.E thickness,etc and they will make it just for you.
will it be worth it in the long run bud!!! sure its nice to have a high revving motor,but weigh ALL ur pros n cons wisely. a high revving motor requires more maintainance and will NOT last as long as a bigger displacement motor.be prepared to run lots of NOS to make up for lost torque lol…
the main question is at the end of the day will it be more capable than a rb26??? Hhmmm
