Here's a link to the
Mather Motorsports - Engine Rebuild
There you will find information on what they did to make that little GA fly! Now for the guys with the extra money to spend, get a DPR Stage V head with pocket porting, 5 angle valve job, raised compression by .5 a point, cloverleaf combustion chamber, and some of his other tweaks, send him a SE-R throttle body that will work with your GA and he'll port matchem for ya. All that would cost less than $1500. I'll have to check the prices, but that's what I would do if I had that much more money. Also I sent DPR the specs for the JWT cams so he should be able to modify the head to amplify the performance gains from the cams.
