Re: Header or Not to Header??
I vote No for these reasons:
1) it's not worth it for the 4 cylinder. Leave it as is, then when it dies get a V8 (you would be surprised how cheap you can do it). I know it's hard to see it now, but trust me on this one. Do it the way you always wanted to do it the first time, or else you are just wasting your money and will regret it. If you like the 4 cylinder for whatever reason (weight) and plan to keep it, then maybe, but see next 2 points.
2) Headers are for higher RPM power, but even then it is marginal improvement (on smaller displacement engines).
3) Headers cause lots of excess underhood heat.
I originally had headers on my I-6 and went to an original exhaust manifold due to clearance issues and underhood heat. I don't regret it. I would do it over the same way again.
