I have a friend looking into Olds BB's for his car. What is a fair price on a pair of rebuildable C heads? He asked me, but I had no idea. I had to come to the experts....

 

small valve 100-150.00
big valve 200-250.00

 

OK, is there any way to tell the difference between the 2?

 

Measure the valves. They are not super accurate but for rough measurements a set of Harbor Freight calipers are a must for any car guy.

 

That has been added to my list of things to buy this weekend. He may not need to check the heads after all. Looks like he's found an early model Toro motor he's interested in. From what I understand, if these are th correct head he should have the big valves?

 

yeah if there correct they should be the large valves and believe me you wont regret them one you get them rebuilt they are awsome on my 442 but i have been hearing i can make more power with so alum heads.

 

I'm going to go with him to check it out. I think he said its a '70. If its real, I'm sure he'll ****** it up.

 

Last year for C heads is '69. '70 heads would be E on a Toronado.

There's some photos on this thread showing the different sized valves.
