Only 2.15" intake valve and they are steel.

What minimum & average CSAs does your "small" port have?

Any more details about the cam you can provide?

Hmmmm... no response. Does this mean I'll have to ask you at Carlisle next year after you frisk me to make sure I'm not recording the conversation? laugh2

Also, you mentioned custom Icon pistons... as in directly from the manufacturer, or modified by someone else? Only asking because I thought they didn't offer anything except their stocking pistons.
