I am going to order some world product sr torquer heads should i get the 76 cc or 67 cc chamber heads for my 305 tpi motor.thanks

 

Stock you have 58cc, so unless you plan on having them mill or are looking for a compression loss, I wouldn't get either.

 

The World Products Torquer S/R 305 heads already come with the stock chamber size of 58cc. Those are the ones you want. If you have '87 or later engine use part # 042750-1. If '86 or older use part# 042650-1. The 2 are different because of the angle on the intake bolts on 87 and later heads/intakes. Later.

 

Definetly get the torquer 305's.

The torquer s/r's have 2.02/1.60 valves that wont fit inside a 305's bore, and you'll definetly loose compression with a 67cc chamber.

 

The Torquer S/R's for the 350 have 2.02/1.6's, but the 305 S/R Torquers have 1.94/1.5's. Make sure you look at the 305 S/R's.

 

The Torquer S/R's for the 350 have 2.02/1.6's, but the 305 S/R Torquers have 1.94/1.5's and are only 58cc's. Make sure you look at the 305 S/R's.

 

Is there any place else that sells these heads? Jegs here in Columbus said they have been on back order for 2 months and don't know when they'll be in. I haven't called Summit yet, but any other place anyone know of? I'm getting ready to do the LT1 intake swap, it would be nice to swap heads while I'm in there.

 

They are backordered at Summit, as well. Unless you can find a shop that has a set in stock, you will have to wait until World Products catches up with the orders. I don't think they planned on the 305 heads selling so well. They probably figured everyone drops the 305 for 350's. Good luck.

Get a set of 350 heads and have the combustion chamber milled down to 58cc (stock compression) and use 1.94/1.5 valves
