Default MS4 with 150 or 200 shot

I have a 99 z28 with ms4 and stock heads forged pistons and rods. The motor made 400hp and like the title said I am looking to hit it with a 150 and a 200 shot. The kit is a 90mm plate and I would like some ideals on what plugs and gaps to use. Thanks!

200 will be fine with that cam as far as gap I would recommend around .32. That is what i ran and had zero problems blowing out spark.

i have the ms4, and have hit it with 150 without a problem. Some guys have done upwards of 250 on this cam. Br7efs would be good plug at .32, If you go to 200 switch it up to an
b8efs. Good luck with the set up, I went a 6.59(1/8) with mine, and it was pig rich. Hope to get her dialed in and do a lil better.
