So yes headers make things better and if you are racing I think that's where you want to be, I think I will just go with my standard exhaust manifolds for now! So my engine is sorted, just got to get the bits to NZ now and start the build, she won't be the perfect build but it will be much better than stock

Holley 4166
Edelbrock performer intake
Summit Sum-6900 Cam
Valve Springs
Lifters
Double Roller Timing Chain
XXX714 Closed Chamber Heads
Hardened Push Rods
Stock Exhaust Manifolds
And an 8.25" with a ratio between 3 and 3.23
