I've also found a source for built heads for the 2.3L ponies. Check out
www.Powerheads.com for replacement heads if you want to go that route. I'm going with a better chip, powerhead's replacement head,sportier cam, and a easier flowing cat back system. Also check out
www.RacerWalsh.com for more 4 banger performance parts. Hope this helps.
