I just bought a motor over the Internet and received it. It was built by trinity and never installed( new motor). I have build sheets , it is +4 stroker , 102mm piston and cylinder, 12.5 to 1. Heres where it gets interesting, seller claimed ported head and +2 valves, and web cam. Trinity has no record of head work. I can see that porting has been done, at least some porting. I also know I can take valve cover off and look at cam. My real question is I would like to know what I got for sure so should I remove head and send it to someone for examination. Port? +2 valves? Cam ? . Any suggestions or recommending of what to do, or who to send it to would be great. Thx!
