Hi Corvette Bob, thanks for the interest in the cylinder head situation, in the end Summit took $200 of the cost of the second head and then reimbursed me for the $200 shipping to Australia so they cost me a total of $1700 shipped for CNC Edelbrocks,
as for the header situation my problem is the car has been converted to right hand drive, the steering shaft runs run up next to the header pipe out of no.2 so I cant use off the shelf headers
only option is aussie made headers for the rhd conversion at $850.

WOW! I'd have never thought you could get them there so inexpensively. Is that $300 to your door, or just the cost of shipping?When you said Summit reimbursed $200 for shipping the head, I figured a set of headers would be somewhat similar to ship. Not so much for the weight of the package, but also the size as well. If headmans are the ones you want, then I guess you're all set!

thanks for the pics tuneport, I like the way the Hedmans on the right side are swept back the way they are, It looks like they might come close to clearing the steering shaft that runs on the right side of the engine on my car
