I was reading in another post that the 85 and 86 blocks have forged pistons, is this true?? If so when I pull my motor for a rebuild and upgrades, next spring, I was going to replace the pistons, but would it be better to just have them cut for the valve reliefs???

if funds are lacking have them cut for reliefs but if using twisted wedge heads not necessary but you said you are using gt-40's so get them cut
