I bought a set of heads site unseen for 125.00 . I took a gamble the casting numbers 10239906 . Low hr motor that froze and busted the block. I'll have my hands on them tomorrow hopefully they have the same accessory bolt holes. Now the fun part I've got a good running tbi motor what do I need to get to swap the heads besides intake? Can I keep my stock exhaust manifolds and plumb a tube to the egr or do I need later model exhaust manifolds? What about rocker arms and pushrods? I realize with stock cam and tune I'm not going to get a major boost in performance, but as long as it doesn't puff smoke on crank up and runs good I'm happy.
