That's the great news i've been hoping to hear! But how thin is it compressed?

I'm still unsure where this 1mm came from. I hope it's really the block height and not crankshaft bolts untight
Sadly, i couldn't find a worthy ST head. They all are busted by now out here... I've thrown away one with wasted cam surfaces and another one i have is fitted with cracks. So i use a blacktop head, measured ~43 cc's in it:

Regular. It's 95 here but another scale. It's not that bad, but it's worse then worldwide 91-92 AFAIK. We also have 98 and 100 here but these are less common and they wouldn't give me a lot of gains i believe. I'd miss 20 hp for more stable gas TBH.

I'm not quite capable to say something about but i have 2 hot sides: 21u (0.46) and Ор6 (0.58). If i'm correct, they'd allow for ~250 and ~300hp before shutting the flow. However i'm really stretching my knowledge here, can't say anything apart from this.

I will not map it myself for sure. Gotta a get some dyno time. Oh i can feel how scared i'll be of that day.

Well, i really hope i'd get a good engine/car. Nobody knows a duck about fast ford phenomenon here and i fell like i need to represent it here.
