whats the reason for going back to 1.7s?
Did you notice a difference in power going to 1.8s?

 

I'm going back to the stock just to see if my mpg's come up any. I did the rockers and the heads at the same time. Just playing with the set up. I'll have the Harland and sharp 1.8 and the valve cover spacers for sale here shortly. just got to swap them out first.

 

I was able to swap from the 1.8 back to the 1.7 and nothing with my tune changed. My power dose come in sooner at lower rpms. I could tell the differnce.
