Thanks,guys I will keep your ideas in mind.My use of stroker plates in this case applies to K models.I have several sets of the short K model cylinders and my intention is to use stroker plates with an increase in stroke to get up to around 55 cubic inches so that anyone in the future would be able to replace the pistons if needed with standard K model pistons instead of having to obtain special made Expensive stroker pistons.Being that K model gaskets are hard to come by I thought it would be beneficial if one were able to elimimate the use of the old gaskets and use O-rings that hopefully would be of a superior design and readlly available at a cheaper price from almost anywhere.It seems that if the moderen bikes are doing this that it would be an improvement.
In reference to the need to modify the intake manifold, it's my understanding that once the short K model cylinders(45 cubic inch) have their height increased by 3/8 to match the later KHK cylinders, I should be able to use any of the later KHK manifolds. Please correct me if I'm wrong. It won't be the first time, and sadly, won't be the last. Thanks again for your help. Tom
