Well you may have seen I pulled the trigger yesterday on a set of unported assembled SM heads.
I did talk to Stan the guy that generally answers the phone or has every time I've called. He said very doubtfully that they would take them back and have them CNC'ed. I reckon tons of people do porting and I can have that done later. Of course I'm still holding on to my what I believe realistic expectations of a lighter head a possible ability to run lower octane and hoping for some more performance but not expecting it..
With that said I know you have shared with us that you haven't seen any major issues but did change the umbrellas? And a couple Springs were a little soft? Is it possible for me to just take these off and have them checked? Maybe when I get them I will post some pictures of the Umbrellas and see if these were the ones that you were talking about? And I do appreciate your help and your experience...
