Paul, I'm retired I have a lot more free time than you. I just watched both of Monty's videos. It looks like if you tap into the rear of both heads then connect to the water cross over on the front...

I have never considered doing that mod. My engine has no cooling problem. By the time I get back to my pit it's down to 170 or 180. If it ain't broke why fix it. I plug bot holes in the rear. I have...

I changed the oil and put in a fresh WIX 51258 filter and 7 quarts of Schaffer 20/40 Supreme 700. Cut the oil filter apart and was pleasantly surprised how clean it was inside. I jetted up from 94/94...
