I dont have any input on reman blocks, but after I do trans work the 910s and push rods are on the docket like @Hit Man X stated.
These blocks are tired at 200k with weak valve springs. Eric's compression is pretty good now that he's got the shimmed 910s.

I still have oil loss..but that is another topic.
I could spin many of my springs by hand. I think all the exhaust took a pile of shims to get that mystical mid 130lb seat pressure. Worth it? YES.
Even a slap on and let it go job would help. My machinist checked my stockers in the low 70s to high 60s at correct height I recall and OE is in low 90s? You take into account my valve wear and seat abuse, I had many in the low 40s. More math via boost pressure and valve diameter showed easy valve float/cracked open at full tilt aka LOW POWER
