S/R Torquer heads no longer available?

I'm doing the careful planning for waking my stock 305 TBI up a bit with breathing and a tune. I visited the world products web site and the only 58cc heads they show are "S/R Stock Replacement". They show no 53cc "S/R Torquer" heads. Anybody know if these used to be available? I'll give them a call Monday.

I got the S/R's from summit last october. The S/R line is the only 305 head world makes that I'm aware of. It's called the World 305 S/R Torquer, but it's listed in the S/R line and not the Torquer.

I would pass those right on up and go for Aluminum ZZ4 heads or 059 casting 305 Vortecs.

If you use the GM intake and plumb it externally into the driverside header it will, otherwise No. The ZZ4s won't let you keep EGR either.

Thanks - IfI keep the car, I'm trying to decide between getting the 305 to breath a little better, chip burning, etc OR just gutting all the plumbing and dropping in around a 300hp 350 with carb. Leaning toward the carb for now. Simpler.
