im not gunna retype what everyone else just said just if you try it dont use the gsr head use the type R way better hands downand ya dont just bolt the thing on and go you need new headers,intake,interanl oil pan,water pump,timing belt ect... dont expect to pay less than 500-600 dollers for that TYPE-R head (so worth the money) and probly around 2500 for instalation and keep another 500 around for parts and other complications that can occour p.s. the frankenstiens have better low end then stock VTEC's
