HEY SAM ARE THESE HEADERS A BOLT ON NO MOD DEAL AND HOW DO THEY COMPARE TO GBODYS. I AM VERY INTERESTED IN PURCHASING THESEI Experienced the same problem with mine. The solution is to make sure the cross over is compressed completely. It's hard but it will compress more! Mine hit the flywheel until I compressed the 2 pieces and presto looks just like pacemakers86 picture!
