Figure I would ask around. So I am putting a 6 bolt back together. Engine had 12k or so on it. It blew a head gasket in 2009 and has been sitting since. Anyways at this point the crankshaft is out of the car and at the machine shop as the engine needed new bearings and the old crankshaft was trash. Guy was running no harmonic balancer. So at this point the head gasket job has almost turned into a full rebuild. The engine was built by slow boy racing and the work has been pretty bad. I have thought of blowing the budget and pulling the pistons out and putting new piston rings in with a fresh hone. I did find that this has some 85.5mm Wiseco pistons, so I guess that is a plus. Here is a picture of the bores today. Would you guys run these or just go ahead and rebuild it all?
