nope.....that cam serves my needs very well for the moment....and the combination puts down pretty good numbers, so I'm staying put. Believe me its tough to not up the cam, but I just want to get it back together and drive the thing.....
I did find some scars inside the motor, I'll email the pics....nothing too crazy, but the valves and the pistons have definitely met each other.....I know it wasn't with these heads, cause they just got thoroughly checked and there was no damage to the valves or pushrods, but at some point in the past, maybe a missed shift?, a weak spring? or too much rpm? because on three of the pistons there are "knicks/gouges/marks" in the top of the piston there the valves likely floated and his the top of the piston....
I found the first one (number6) when I was experimenting with cleaning the top of the pistons and at first thought it was simple carbon, but low and behold there was a small amount of displaced metal (ouch) so after cleaning the top of the piston with a scotchbright pad and lots of elbow grease, I masked off the entire area and got out the air grinder and a scotch bright disk and lightly removed the ridge that existed if only to eliminate a hot spot and the potential for it to flake off and tear up the cylinder......nothing like having fun.....now I have to clean off the other 7 pistons, tap all the head bolt holes and get them clean and dry....then bolt the heads on and....and...and...well you get the idea...
