clayed one piston and threw a head on and 1 chain, everything seemed to clear, no marks and we put enough clay to come up past the valve reliefs. I didnt use a checker spring but this gives me an idea, i have tons of clearance .I dont know why they put such deep reliefs in the pistons. also took everything apart, bearings look fine, crank and rods look fine. So it looks like a new set of pistons, rings, head gaskets, machine work and ill proly throw new bearings in it
Question about these TFS heads, wouldnt the valves in the head have more clearance than stock 2v heads? this is what i herd, because they took out angle?
