As far as I know, Pro Topline is out of business. Do you have a used set, or some RHS heads?

Re: how good are protop line heads

I have no hands-on experience with them, but the reputation for flow was pretty good. I did hear some gripes about porosity in the aluminum versions, but only rumors I can't really attest to myself.

235cc is a huge runner for a small-block. How big is it?

Nope, Comp Cams. Revised versions are now sold under Racing Head Service (Comp Cams).

Re: how good are protop line heads

Used a pair of 200cc ProToplines on a 327 and later on a 350 blower motor. Both ran very well. We did pull the threads on a stud on one head, but I think the owner over rev'd it and floated the valves.

I haven't used the 235's but have heard good things about flow. Have also heard quality is hit and miss on heads built before Comp took them over.
