I ended up ordering the wrong set of heads for my engine, and I need to get the correct set. Here is the information on the heads I am selling:

http://www.protopline.com/223400020a.htm
- .600" lift valve springs for hydraulic or solid lifter cams
-Straight plug design

I installed the heads on the small block, but never ran the engine. They have orange engine paint on them. I am asking $610 or best offer for the pair. If you need more information please let me know.

are there steam holes that would allow them to mounted on a 400?

 

steam holes are easy to drill

are they? from what I have read they have to be done fairly accurately and on a specific angle so the meet in the middle. But I've never done a set.

 

maybe Im wrong here, cause ive never done this, but from what I recall all you gotta do is line up the head gasket, and drill the holes in between the CC's. one hole between two cyl.s is all. try running a search on doin that. some has to have written about it on the net. Im too lazy to search myself.

 

what I have seen is magazine articles, and they show you drilling in a little using the gasket as a template, and then drilling on an angle from each hole such that they meet in the middle

 

$450.00 and I'll come get them
