Back to the potting part looks like my ports are spread out more than yours Mike but from what I'm gathering it's best to match manifolds and the head to the gasket and possibly if I got bigger than the gasket to match the gasket? Anyone wouldn't happen to have pics like Mike's but with the style of head I have would they? Just to give me a little idea. I have done a little bit of research on the beehive springs as well. I see so many pros from them. What are the cons? Should someone be cautious about shimming a valve spring? They are a smaller spring with less metal and can still handle high rpms, but how durable are they?
