well, the head is off the motor , the cyl looks perfect ,like nothin happend.
the valves look rusty , i think there is some kind of cyl pressuer leak.
will check the valve seating on the valve port and check the valves for any damage.
thats it. thanks for posting guys
as for your questions these valves are less than 25 miles old
the timing was programmed in iridumes thats why( i think)
but why only 2 out of 8 are bad???? btw they are 3 and 5
i used AutoLite XtremePerformance Iridiums and they are way better than NGK laser iridiums IMHO and they last longer
the heads are off foxxer
