You Will be amazed what proper carb tuning will do. It will crisp that motor up a lot. Its not too big as mentioned but there are a lot better street carbs out there out of the box if your not a carb guru. We will give that 850 another chance. Will be interesting to tune it together with the A/F meter.

Personally, if the piston is only 0.020" down, I would zero deck the block.
If you do this now, you will have several nice future options for aluminum cylinder heads with quench and a decent compression ratio. We would probably have done that, but my buddy wants to get it ready and the machine shop have no time to deck it the next two weeks.

Will have the block back for the weekend, cleaned, with new bearings everywhere, checked bores and rings and ready to assemble. Both crank and cam has been polished. Hopefully a new cam gear with possibilities to get 6 degrees advance will land here too before weekend. A new high volume oil pump is already here.
Will cc the heads, and another machine shop will stand ready to mill them on Monday. Hopefully I can find a valve spring tester too.
Came to think of one thing today. My buddy mounted a hood insulation, and with the RPM intake the Twin Air top gets choked by the insulation, and the height of the filter is only 2". Do you think this might have affected the breathing..?
How much cylinder pressure can we expect this combo (with 9.5:1) have?
Well how much torque and hp would it give?

Pay attention to timing chain selection , you need to spend money to get a good one that is more adjustable and is able to use offset bushings if needed , the low cost ones will have a SLOT instead of a hole for the dowel pin , good luck drilling a hole for the bushing.

Update:
Same Comp cam went back in. My buddy is a little cheap so he bought MrGasket offset bushings and I drilled the cam gear so much I could and put in a 6 degree bushing and got 102.5 degrees centerline, 3.5 degrees advanced from 106 (this means that the cam was installed 2.5 degrees retarded and that explains a little). Had wished for 5-6 degrees advance but I couldn't get more with this cheap crap.
Shaved the heads .020 and got 10.17:1
Still no adjustable rockers so preload is hard to measure. All I can say is that is is very little preload. Hope he can spend a little on used steel rockers some day.
Painted engine bay yesterday and will paint the engine today and, hopefully, will get it in so I can install the exhaust and get it running by Wednesday.

Should be no lash with a hydraulic cam. So what are you meaning to say?
R. Did I say lash? It should be preload, sorry!
