did you de-shroud your heads or did you leave the sharp overhangs?
I've had two engine failures this summer ( first was a shady tune from some dude, second the rebuild was done too tight for my use ) so I finally decided to do my own ****. If I'm breakin' it, well it will be MY FAULT. I'm still the one paying in the end...
So no, I haven't done anything to the heads besides to have them checked, and **** me, my LH head is starting to be noisy. I guess a valve guide is going on me. I'll take the engine out again this winter, but please, enlighten me on said overhangs ? Never heard of that. I have the big-port V7 heads.
