United Pot Smoker Posted August 13, 2004 Report Share Posted August 13, 2004 i have a stock head that was modified by trinity racing. i bought it off a guy a while back and never put it on. i know its shaved .085 and it has the pollish work done two it and its pitted or what not. the guy i bought it from said it makes the engine run cooler and adds compression and makes the engine burn fuel more efficiently. i bought it for $100 off him and would like to know you guys oppinions on it. it looks the same as this picture. thanks http://www.trinityracing.com/products/yama...eeheadmods.html Quote Link to comment Share on other sites More sharing options...
orion6781 Posted August 13, 2004 Report Share Posted August 13, 2004 .085 is alot to be shaved the only way i can see it making it run cooler is because you would have to run race gas anbd that burns at a lower temp. Quote Link to comment Share on other sites More sharing options...
