**NEW Edelbrock Victor Series Small Block Heads**

"They also feature the W5 bolt pattern and have raised exhaust ports". What does this mean? Looking at the head bolt holes, are they set up for a different head bolt pattern? Where are the front and rear most exhaust side headbolt holes?

They have the extra head bolts for Aftermarket Blocks. You should be able to use these on a factory block, just dont use those head bolts.
