Plugs & wires - Vortec 8.1 on W22

[osgoor]

The plugs and wires in my 2005 Itasca Suncruiser are original and I am thinking they need changing. I have not looked at the current condition yet but power, idle and mileage (even with Banks Power installed) are not great. According to the service manual the plugs are AC Delco 41-983's. For those of you that have changed their plugs, did you stay with AC or did you find a better performing brand? Also, what plug wires did you go with?

Also, any tips on finding the screws to get me in the dog house?
Thanks!

I bought magnum wires & plugs from Glenn @ OEM engineering two years ago used a/c plugs & gapped @ 0.60 they have been working fine I get about 7.5 going 60 mph no other engine mods.The two screws were hidden in the carpet next to the dash on the sides in the center. I left them out the latch works fine.
