I have done extensive research on the 4g63 head swap onto the 4g64. However, there is only one thing left I still have questions on.
I have read conflicting posts about how you do or do not have to swap pistons from the 2g 4g64 to have valve reliefs for the 2g 4g63 heads.
I have to do head gaskets anyways, and I'm in no hurry to get the truck on the road besides passing inspection, so I figured I would go ahead and do it. I plan to turbo it later on, and a replacement, nice cam for a SOHC seems to be more expensive for smaller power than I want to endeavor into.
