which spark plugs for e85 and mp122 maggie I bought the NGK 4177 v-power spark plugs (tr6)and after looking at them I see the electrode sticks out pretty far. I also don't like the sharp edges on the v electrode. any thoughts on spark plugs or will these work? I should be around 9psi boost wise if i am lucky.

I would run 8's, no performance increase by running the hotter 6's and you might be able to sneak in a little more timing. What I use on all my LSx stuff and even my NA stuff is
NGK R5724-8
which is a non projected 8 range plug, its perfect for boosted stuff even with E85

ive ran 6s on E85 up over 800whp, not something I would do again as there is no benefit only negatives.
My NA setup actually went a few hundredths faster and .4mph more switching to 8's at the track with no other changes. Got rid of any knock I was getting and after was able to add 2* timing and pick up more
