Obviously we are not going to supply a return engine with problem or damaged external components and accessories. If any customer wishes they can send there engine and we can do the upgrade and complete remake on their engine for the same price, we just need 3-4 weeks for turnaround time to complete and reship with all their original equipment and version.

Best Regards,
Ray @ Raylar

I agree Alex/Haxor, it is a well developed package. I particularly like the fact it addresses the engines primary shortcoming, the cylinder head.
