RE: 4V swap

Buy the whole 4V. Don't go the swap the 4V heads onto your 2V block route. It's a pretty easy swap not much different than just putting a different 2V in your car.

RE: 4V swap

I would get a whole new setup. I swapped my 4v heads onto my 2v block and I with I got a whole setup. The cobra motors will have a higher compression than if you just swapped the heads. The only thing that was nice out of doing my swap was that all the gaskets are new. I noticed a huge power difference but with the whole swap there could prob ba a little more.

did you swap pistons? doesnt just puting the heads on there make the CR like 8.0:1.
