headers on a 65...on a BUDGET? Aint gonna happen. All are $$$. Cheapest believe it or not are going to be $400 68 340 logs and they will work great. Hookers fit, Thorleys fit better. old Hedman's are wacky looking but probably breath the best due to their generous turns. Even logs on a 360 will work as the car is so light and the 360 has so much low end torque that youll blow traction before you know it and itll just keep coming. Headers are nice, logs fit and there is not much difference on a stock 360.
