My dad had the valves on the heads recessed or put higher in the head to avoid the pistons hitting. I remember saying this. The cam i don't remember.
Is it just me or is this not really a solution? No matter how high you back stuff the valves in any head you still need to check for valve clearance. You aren't just looking for room between valve and piston but you are also looking for room between valve and cylinder wall when you are considering camshaft in a W motor correct?

Update

Got my suspension painted up with POR15. A arms springs and tie rod ends look good.
Also found 656 409 that I'm probably gonna get.
One last thing. Traded my 65 exhaust manifolds for 64 exhaust manifolds. I couldn't fit the manifolds with center link and idler arm. The 64 manifolds fit and work better. 20210202_154355.jpg20210202_154406.jpg20210202_154419.jpg20210202_154425.jpg20210202_154429.jpg20210202_154445.jpg20210202_154451.jpg20210202_154501.jpg20210202_154506.jpg

You can't really use a piston but a caliper set at 1 1/2 inch down all the way around will let you check..018 on a 4.155 bore is nice on a n/a combo.See if the second ring comes in between .018-.022 if so you're good for a pretty warm streeter.

Great news. Got the block back and looks great. Had the machine shop assembled the short block. Only thing I can see is the number 6 piston sticks out of the block as the rest are under the deck. Took a feeler gauge and it seems the number 6 piston about .006-.007 out of the block. The rest seems to be .004-.002 under the deck. Is this normal?

Did they put the wrong length rod back in it? Wild! :drop

I was measuring all the pistons heights and the conclusion I've seen is the right side of engine is about .005+/- lower than left side. Pistons heights on 1,3,5,7 are -.002,-.003,-.003,-.002 under the deck. 2,4,6,8 are +.004,+.004,+.006,+.004 above the deck.
Curious as to how you are measuring. Is the deck height been milled further on one side than the other? Also when you rotate the crank to position each piston are you trying to use the timing tab on the harmonic balancer? Just wondering.
