Thank you guys for your suggestions. I guess I'm just a bit burned-out on the car and I'm not in the mood to sink maximum dollars into the J-heads. But, maybe the J-heads will work out.

I may just ship the heads down to Shady Dell or bring the whole motor down there for a rebuild.

I've emailed the owner and he has been helpful in giving me some direction. Obviously, stroking it will give me more power.

I guess it comes down to how much money and time I want to spend on this. Just in a period of frustration right now...lol.
