G52B head

[natureboy]

I've seen a couple of heads for the G52B on ebay recently at what appears to be a good price. Is there any benefit to this head on an n/a G54B over the stock head, better flow or anything? I've got a Caravan nonjet head on right now, but I've got a persistent clicking on cyl 4 valves that won't go away no matter how I adjust them (obviously mechanical lifters going on here). Smaller or equal vavle diameters? No good reason to swap?
Thanks

Thanks, I'll give a try this weekend and let you know.
