4.0L head on 4.2L engine

I have read the write-up by Tony Carricaburu on installing a 4.0L head on a 4.2L engine and I have several questions. Where does the 40 additional HP come from? Better breathing? Higher compression ratio? etc.
I live and play at 7200 feet and above. The 4.2L engine in my 1988 Wrangler YJ is anemic at these altitudes and I am looking for a reasonable way to gain some HP without creating engine problems.
Does anyone know how I can contact Tony. E-mail address would be helpful if it is OK with Tony.

Thanks,
Dick Osterhof

Re: 4.0L head on 4.2L engine

John's site is a good one, and he's pretty easy to get ahold of if you have any questions. I can attest to the hp gain, I've ridden in his Jeep many times, wheel with him, and have spotted for the heavy footed guy [img]images/graemlins/grin.gif[/img] twice in competitions. BUT, his high teck 4.0 head mopar FI CJ was only a few tenths quicker than my slightly tweaked Weber equipped 258 in the sand drags last weekend! [img]images/graemlins/cool.gif[/img]
