Did you put sleeves in the 3 outter exhaust head bolt holes in your tiger heads ?

I'm positive the backfire was ignition wires, 2 year old Taylors, cracked and arcing on the firewall intermittently
I put the sleeves on the center bolts only. I think I will do the outers next time apart..
15* is a starting point because I have no Idea where the boost will end up.
