In my prior post to you I stated that you can use a cylinder and head from a different year without any problems. But, you need the cylinder, head and coolant intake. The PV pieces are the same. GG used TM motors prior to 97'. Then continued to make subtle changes to there own design until present. What has always remained the same is the bore and stroke. With maybe some changes in porting. The guru's will chime in at this point and make any corrections?
