289 mustang C code - header debate
Hi all, looking for some input on this.
As the title says I have an old Mustang. I purchased long tubes, 600cfm vac secondary Holley, 4bbl intake. Installed everything all is well.
The exhaust is still a single tube exhaust but was in rough shape. I’m going to a dual exhaust system custom fabricated.
A few years back I pick up some headman headers.
The problem is I really don’t want to weld the power steering drop down bar and loose ground clearance.
Have to get high temp plugs do all the BS that comes with headers.
I have the original log manifolds, does it
honestly make that big of difference on a street car?
If i did other engine mods like a mild cam would the original manifolds make that pointless in the future?
Are K code manifolds worth it? $600 price
