Hey, just like nobody knows the PD clearance, nobody can truly be right about anything here.
I don't agree with everything you posted, wish I had my stack of cracked and max ported x. j, u heads from back in the day. Can J heads be made to work, likely, not my place to debate it with you or anyone else. Just like you seem to feel there are people supporting certain items, the same can be said going your direction. You LOVE your J heads. You have a viewpoint and are welcome to it without a doubt. Does it fit with the op's desire? Not so sure.
Looks like a few personal barbs/digs in here towards people.
