These will fit your astro v8 , I have patriot angle plug heads, only mod is to dimple #1 tube to clear #3 spark plug, of course use shorty plugs, passenger rear bolt is a bear but other than that, perfect fit!!! I am very happy with them !!
The headers arrived in a beat-up box on time with the contents in perfect shape. I guess that's why these things are called scratch and dent headers. No issues except that the collectors are the 2.5 inch variety with a colletctor adapter that bolts to the collector which is the correct size of 2.25 inch. The headers are a really good design as compact as these manifolds appear. I can't wait to try them on for performance.
Just a few small bends at end of headers where collectors bolt on. Took a pair of players and pretty much bent it in the places bent. Excellent deal for the money. Would definitely by again.
