Hey i was wondering if anyone could help me out with the thunder tiger pro 70bx engine?I have 2 old ek4 trucks i was gonna get going but noticed neither of them have a head shim.One has the msj head the other i believe is stock .I can't find any info on the shim thickness so i can't even make one.Do i even need a shim?I'm not sure but i think when switching to the msj head it said you didn't need the shim but its been so long i don't remember.If anyone could help it would be greatly appreciated...thanks
