Digifant or K Jet - Which Head had biggest valves? if any?

Morning Everyone,

I am doing a carb conversion, and wondered which of the two GTi heads had the biggest/best valves?
Also is there any difference in flow?
Which would suit a carb conversion best?

Just want to fit the best of the two, not looking for a trick head, or a special, just a simple bolt on job that will let my carb, which is a single 42 DCOE on a Lynx manifold, breath the best??

Thanks guys

as for the heads i don't believe there is any difference valve / port wise

Early K-Jet engines had hotter cams, but we're talking about 1600 era here. There were a couple of variations of 1800 though. So, flow, yes there's a difference, and generally the earlier the better. As far as valves go though, I think they're all the same. Remember you can't just swap an early cam to a later engine though, you need to match depending on mechanical or hydraulic tappets.

As with all requests it helps if we know what you have to start with
