our cylinder heads and stamped blocks are irreplaceable. But if they have major damage, DO NOT THROW THEM AWAY ! I recently had two very large exhaust manifolds repaired by a local guy after a quote of $14,300 to replace them.... This local guy [ Auburn, WA ] does work on antique and race motors that have blown up.
he made a very nice repair to the manifolds and they are working perfectly.... Aluminum Head Welders 253-931-1148 If you want to save these parts<img src=images/icon_smile_big.gif border=0 align=middle><img src=images/icon_smile_big.gif border=0 align=middle>
