Actually I'm looking for a set of 920 heads to do this project. I want to leave this engine intact as it's a great running little engine with less than 5000 on it. But I'm willing to spend a few bucks to test my thoughts and build a set of 920's for the project. Maybe I take it to the dyno then install my factory 1.88 J heads stock nice valve job and compare the difference in MPG and power.
