Anyone know where's a good place to get a top end set for a 550. Mine's a 78', but i'm told the other years are the same. To anyone out there doing a rebuild, DO NOT go for the athena set. I order a "complete" set for my rebuild and it didn't have the o-rings for oil galleries on the top of the block. So I tried to find a suitable match and thought I had. But judging by the oil running down the fins, I guess it didn't seal off like I thought it would. But anyway, back to my original question, I need a place to order a top end set??? Any ideas?? A place in the states would be nice, but i'm open to suggestions elsewhere.
