Questions about stock 350 heads.
What is the casting number for the stock 350 heads, isn't 882?
Does anyone have flow numbers on this?
Would a stock 350 head make a good performance upgrade for a 305, provided its milled down to 58cc of cource.

The stock 350 L98 f-body iron head is 14101083, its 64cc combustion chamber, and no its not worth putting on a 305. I would suggest some 305 specific heads, or just port match your stock heads and save up for a 350 engine.

If you mill down the Head, Your intake will more than likely not sit right on your block.
