| Hi RCGBOB44
Nothing that they do with the testastretta head will help the older engines. Theres a more efficient oil path in the new engines and thats it.
My original post was just to say that its not all doom and gloom with rockers. I did not need any. Perhaps i don't rev it high enough. I do use Ester based oil and change it every 1500 miles though.
