did you ever find out ?
I was just wondering if you ever found out about the Strike Force heads ? I am trying to keep in mind where all these "new" brand name alum heads are cast. I have no use what so ever for PC. Seen way too much damage even with Brand Name parts installed. Seems the real issue is the actual type of casting as well as the actual material used. Like building a house on a jello foundation. I have seen 3-4 'shops' selling their own brand name of head. I have pressured a few that have finally broke down and told me their heads were cast in the same foundry as PC but theirs are pressure cast and not sand cast like the PC. Sounds kinda hinkey to me. My preference is to stay as far away from PC as possible. Bare castings or complete makes no sense to chance a motor over a few bucks considering the reputation they have buy the real hands on race folks.
To each his own I guess.
