I'm willing to build my own motor and want to build it right the first time. Does the 20R head bolt directly to the 22R or do I have to do some modifications? Also, what are my tranny options when doing this swap? Are there any that will bolt right in, or am I going to have to do some drive line modifications? I plan on drivin on the 20R until I have the 22R ready to drop in. I figure that once I do the swap, I'd keep the 20R around and rebuild it as a spare motor just incase!
