echo $_product->getAttributeText('attribute_code');


//for TEXT attribute add
echo  $_product->getData('attribute_code');

3) these new attributes will display below the product  description

4) then in your product detail template display these blocks 
echo  $_product->getData('attribute_code');

make sure you have access to $_product or $product:

$product_id = Mage::registry("current_product")->getId();
  
$product = Mage::getModel('catalog/product')->load($product_id);
