For now I will be running my 1 3/4" TTI headers. Unless I run into a nice used set prior to install. I don't think I am going to bother porting the stealths. Eventually I plan to upgrade to Trick Flows. Right now it is use what I have to get next spring rolling. Main reason for the build is my 440 is tired. Blow bye like no other on the passenger side. When It is warm outside and car it up to temp. Oil pressure fades bad. Which it never use to do. It was a cheap $500 stock short block I picked 8 years ago and slapped together for my 76 Power Wagon. Then found its way into my Demon 5 years ago. I just want a healthy short block put together and use what I have the best I can. Then I can upgrade over time but who knows that may change as well. I haven't even started the build yet.
