I was doing some searching today, and noticed that apparently Srt-4 plugs are NOT a good idea to use in L61's.
Skunk and Da Squirl even made posts about it, so I was amaized when I did a search and did not find an article!
Great to know that I've been running the wrong plugs for how long now....
I was using LTZR5A-13's
I'm looking for something equivelent, but at a proper 25mm reach......
Is PTR5A_13 a suitable replacement?

I measured the stock ac delco's againts LZTR5A-13's and the ltz's are protrude 2mm longer.

those r iridium, be careful when galling them. I run the ltr6ix-11 gapped at .036, although Ima bring it down to .032 when I get more time
So all in all the NGK iridiums are the best for boost?
