Does anyone have any info on the pro top line heads.
Buddy of mine has new set (235's) brand new in the box
for sale. Heads are cast iron.

I've had friends that have used the heads in the past and they were very good. I didn't realize they made cast iron heads though.

They went out of business around 6-7 years ago. As mentioned above, RHS (Racing Head Service) bought the machinery. I don't know if the plant is still in New Zealand, or if RHS moved the machinery to Memphis.

They made a wide variety of heads, from stock replacement to Vortec to aluminum high performance. I would say their cast iron heads were on par with World products, but I have no experience with their aluminum heads.

Are you looking at a used pair?

I have 2 pair of the cast iron pro topline heads... I have yet to use them, but they look like a decent head, alot better than any of the old GM heads...
