Where do you come up with all this nonsense?
Blah blah blah
For most practical purposes a 20r heap swap is not worth the trouble. Don't believe all the hype.
You've got to be kidding me! If you've got the head off and have access to the parts and/or a bit of $$ you're dumb not to (unless you want "factory EFI" later or something like that) I've got an easy 150+ in mine and I went easy on the overbore. Could have built my own LC stroker, but didn't need a new crank. 6500 RPMs and it's beggin for more. Runs like a scalded turtle!!

Don't knock it till you try it.
