How can adding something increase clearance?

is that a serious question ? ever heard of a shim ?
you make something bigger than it is, tighten everything down, make adjustments and remove the shim = clearance, real simple

Exhaust wrap doesn't actually take up that much space to act as a shim as well as it being compressible. It isn't acting as the kind of shim you think it is in this case. Its not like you added a shim between the head and header to angle the headed. You remove it and the bolts that hold the manifolds to the head will pull both together again.
How does wrapping the whole pipe help with clearance issues anyhow?
I don't know who you are trying to fool or what you are trying to gain, but its clear the header was wrapped. Sure, a better quality manifold may have lasted longer, but wrap is detrimental an any rate.

It will cause the header pipes to over heat as well as to rust faster.
still getting random P0302, sometimes it stays and sometimes it goes away,
Today's compression numbers are as follows:
cyl
1 @ 163
2 @ 148, 154 wet*
3 @ 166
4 @ 177
5 @ 166
6 @ 166
* "If the compression comes up markedly, 40 PSI or more, the trouble is poor ring to bore sealing. If compression doesn't increase much, about 5 PSI, then the problem is probably with the valves. It could also be pulled head studs or a warped cylinder head."
Leak Down test yielded that cyl 2 was operating well into the green range and good to go.
which leads me to believe that this is a possible lifter problem, since this compression is still low after Head Swap

for future ring reference
"A sealed power H802CP or H825CP should be a exact replacement for that piston. It depends on the size of the rings you have right now. Its just the regular cast hypereutectic piston. On the 802, ring 1 is 1.5mm and ring 2 is 4.0 mm. On the 825, ring 1 is 5/64 and ring 2 is 3/16. Don's ask me why one is standard and one is metric. Thats just how it is listed. Or if you have the oem piston number, the 802 is a cross reference of 53020507. The 825 is a cross reference of 4798329"

Oh, that doesn't look good. Can the cylinder be cleaned up and a new piston installed or are you looking at rebuilding/replacing the engine?
