Happy Time is the cheap, rather crude engine from china. It is the most common one you see here in the forum.

ie Do you have a billet hi-comp head?
Neither of them has a longer stroke. Was your's custom-made?
Finally, what's 5 fal?

Right, I understand 5 thou, (0.005").
(Not doubting what you say.)
Did Tony also do the 'stroking'?
(Long-stroke crankshaft. A longer 'crank' won't give a longer stroke.)
If so I have a couple of questions for him.
Since you're looking for performance, I recommend the billet hi-comp head. 16:1 CR vs 6:1
Noticeable improvement in power right through the rev range.
Only drawback is that you need longer than standard studs.
