How much are you going to drive it? If you aren't going to drive it a ton then feed it some av gas or race gas. If you're planning to drive it a lot then you'll need to make a change. Do you have enough information to calculate what the compression ratio is?
I thought the eddy heads are 88 cc and that would be 11.1 : 1 But if they are actually 75 cc then it is more like 12.8 : 1
the '75' stamped in the head is not a great sign for me...
Which heads are they , the regular eddy heads , which I believe were 84cc , the head they made for step head pistons was 88 and only the newer e streets were 75 .
