Pull the heads and inspect the mating areas closely for defects.
If there are none, make sure that you're torquing the head down to spec.
If all else fails, get your stock head rechambered by Brandon at Mull. Stock type head gaskets are much more reliable, plus you will get a dome custom cut to your bike.

I say go for the cheetah.
Tons of bottom end grunt that blends seamlessly into that top end rush.
WAY more enjoyable to ride and much less tiring than the cub.
Dude you're more interested in putting me down than anything else. I bet you can hardly sleep at night huh.
Give it a break my friend. That engine rick built IS made for all bottom end. He has 700 X the experience you have building engines. I would love for you two to discuss it formaly. Perhaps I can arrange a meeting.
Even you said you ran a head cut .030", when daj said it would destroy the engine, but you could care less about attacking him.
All I am saying is that if you are going o stick with pump gas cut your head .025-.030". If you want a better setup get custom domes or let Brandon mill your head for cheaper. Most people do not need a cool head plain and simple.
You just can't stand to see me win. It is pathetic. Like a little girl.
Makes sense to me.
I think it is safe to say that an off the shelf cool head dome isn't going to be a significant increase in performance over the stock milled head. Nor will the cooling properties be significantly better.
If you want something significantly better than the stock milled head you need domes custom cut to your app.
So we have about 80% of the voters that say the cool head is worth it, compared to probably 10% in real life who really truthfully could benifit from one.
But I'm the brainwashed one
I believe you are being overly conservative, but that is just my opinion.
I think that .025" would be a good safe conservative number.
But I hate to argue over .005" so let's just agree to disagree.
