Which Headers to buy? HELP

I'll second that - TTI are the best!
* Went on easier than expected. (Follow directions.)
* Plenty of clearance. (Make sure your chassis isn't "tweaked" or engine/trans mounts aren't worn/sagging.)
* Don't have oil pan clearance problems with aftermarket pans.
* Right angle oil filter adapter not needed.
* Mini-starters can be removed without a problem.
* Inner & outer coating options are durable and strongly recommended.
* Stepped primaries work great on everything from street cars to race cars!
* Plenty of ground clearance.
