My friend owns a 1990 Honda CRX Si, and wants to do a Mini Me Head Swap. He's looking to swap out the A6 head with a Y8, as it offers higher compression than a Z6. My question is, where can he find a complete head other than a junkyard? I've been searching google to no success. And ebay doesn't look to promising. Also, is there anything besides the head he would need? Any suggestions and help would be appreciated.
