I had asked the list about plugs a few months back but got no replies.
So I asked
the guys at my favorite parts store. They came up with Delco R45TS.
I've installed the Dart Iron Eagle Vortec heads on my rebuilt 60 over
327 short block.
They worked good. I have done stuff to the original distributer like a
Mallory E-spark
conversion, mechanical advance kit, MSI cap, rotor, wires, 14 deg vacuum
canister,
and a Blue Streak coil. The parts guy, Bob (he has a 454 Vette) selected
some Platinum plugs
that work even better. They're Delco A41-905's.
I think you should find a better parts store. ;-)

Anybody know if Delco 41-932 ("Professional Platinum") plugs would be good
for my 1958 283 w/ HEI? I currently have Champion RV15YC4 plugs and the
Delcos are supposed to cross-reference, but the guy at the store was clearly
very aggravated by my asking for a plug by number instead of him being able
to look it up by year, make, and model of the vehicle. When I told him that
it's a 1958 block with a 1980-something HEI distributor, he said "well
somebody f-d up your car". I'm so glad he told me that because I had no
idea. Needless to say I don't necessarily trust his judgment.
Thanks,

John- The question is, what year are your heads? Chevy went to the small
"peanut" plugs in about 1970. I would suggest you buy the plugs appropriate
for your heads and them gap them for the HEI, being about .050.

John- If your engine is using the smaller plugs, I would suggest a set of
25s. I prefer Autolites, but Champion makes them also. These should fit
your heads and have the appropriate heat range.
