Pro Comp 175cc Heads

[JBeezy53]

I have done a few searches and found info on the 190 and 210 heads but not the 175s.
So has anyone recently purchased these?
Pros and cons?

Also I hear they fixed the guide plate and valve guide problem they were having with the early sets.

I'm really just looking for feedback and maybe some numbers from anyone with the 175cc heads.

Thanks.
