The cnc345 is really better with a 2.25” intake valve.
Were those used in the EZ heads?
The Big EZ comes with a 2.19 intake but Best Machine opened the heads up to 2.250. So we'll be able to swap the 2.250 intakes over to the -1 heads. We kind of have to go this way anyway since the Big EZ castings are not available at the moment. The other choice was to step up to the 572-13 heads but that was going to be a bunch more money and time to replace pistons as well as other parts.
