Horsepower guess?

Ahhh...then I am thinking about it.

I have this complete rebuilt short block with stock pistons already in it. I would love the kb107's but hate to rip it apart...plus the money too....because

I am going to be spending more than I thought on upgrading the Magnum heads to different springs. When I bought them I was thinking I could use the stock Magnum springs. My fault for not doing enough research before I spent the money.

If I could get away with the Magnum stock springs I could use that money on the pistons.......hmmm...this is sounding kinda whiney....

Not whining, just talking.
