Unless you are stuck with them, DON'T buy the old SB2's. Unless you get them complete with everything with spares, buying stuff for it will get real expensive. There is a set on ebay 559 castings, no valvetrain. Header flanges look the same as mine. The 011 2.2 castings are what you want to find.
I have a complete engine. I need headers and was wondering if headers were interchangable between the two. Thanks for the input, your right this thing is very expensive.
I found a header builder (Lemons Headers) here in California. I had rockers built by T&D. Parts are expensive. I have too much invested to back out now. Engine will be complete as soon as headers are done approx. 6 weeks.
Thanks for the help guys!
I was able to have a set of shaft rockers made up by TD Machine. Really high quality work (along with the price). I should be getting my haeders in about 3 weeks, can't wait to try this thing out!
