the following is an excerpt from www.the-race-shop.com and in case you havnt heard of them they are the ones that built the first header for a HO quad that dynoed a gain of 20whp on a stock engine..they're looking to fit it in a Jbody but will need alittle help,so if you can please do

Quote:

We also have a 2.4L header ready for the 2.4L guys with N bodies, and we are working on a 2.4L / 2.3L design for J bodies as well in the final testing phase. The prices will be the same as the current configuration. Also we are working on a complete line of Ecotec headers from everything from the N and J bodies to the Saturn Ion Redline. We are looking for someone in the Pittsburgh area who owns a 2.4L N body and a 2.3L and/or 2.4L J body for a test fitment on the headers. If anyone is interested in coming by our shop, please let us know.
