Will the s/r torquer 305 heads fit on a 350? I have a 305tbi thats on her last leg... I bought the heads used... Will they fit on a 350, or should i replace motor with another 305?? thanks..

 

It's what I'm running.

Mine have 64cc chambers, by the way.

 

Hello, where did you get those SR Torquer heads from? I would love a set for my 305. Is that company still around in Sterling Heights, MI? Please let me knowif you would like to sell them.

 

I picked up mine from Competition Products back in 2001. I got them bare with their "completion kit" and upgraded springs.

I would not consider them "bolt on" parts. The valve bowls are not very clean, even less so than some stock heads, and a basic bowl job (pocket porting) should be considered mandatory for best results. In my opinion.

The heads are available from Summit, $380 for assembled, $250-$260 bare. The 42650 are '86-earlier intake bolt pattern, 42750 are '87-later intake bolt pattern. CP doesn't appear to carry them anymore (at least not for on-line ordering - can't get their catalog to load).

 

The original poster got their set from me.

Chris, the 305 S/R Torquers will work on a 350. They actually even have 350 combustion chambers, however their volume is not the same as the 350. 350's most commonly use 64cc chambers, while 305's use 58cc. If you put the 58cc heads on a 350 it will increase the compression, and you should be okay as long as you arent running domed pistons on the 350.

 

Check the chambers of the S/R Torquer 305's. As I said, mine turned out to be 64cc. Others have reported the same.

If you assume they're 58cc, your final compression on a 350 could be much lower than you expect.
