I have these Merlin Heads that are machine shop fresh and was wondering if anyone had the specs on these. They are stock, No modification and in like "New" condition. I know they have 2.19/1.88 valves, They are rectangular port. I'm pretty sure they are 119cc and not sure of the runner size. If anyone has any info on these and could let me know I'd apprciate it, Thanks

Well Thanks anyways Guys, I called Bill Mitchell racing and they gave me specs. Just incase anyone is interested, The specs are 2.19 intake 1.88 exhaust, 119 CC and 345 Runners.
