Swirl port head comparison
I have a 383 TBI that has ProTopline Swirl Port Heads (driect replacement for GM # 14102193 350 TBI heads). Does anyone know if the ProToplines are any better than the GM castings? They clearly still have the intake "ramp" in the port, I just am hoping that they are designed better that what I read about the stock ones.

thanks,
Keith

Can you post a pic of the intake port and of the heads overall?

Hate to be the one to say it but those just look like warmed over stock 193 heads.

Yah, that's what I thought, but was hopping someone had different experiance w/ them. They are sold as direct 193 replacements.
Time to start saving the pennies for new heads. Maybe next year.
