I bought some Dart Iron Eagle 180cc heads off the fleabay the other day. Based upon everything I read that Grumpy posted and everything I could gather by looking at various cross section torque calculators and formulas I determined that they were the best casting to being porting from.
The bonus was the pair of heads was like 350 bucks, and they were already cut for the 2.05" valve i wanted.
The 180cc heads were already really good and wet flow testing showed them to be as good as their new platinum line so they didnt get updated. So this was a bonus to me.
So here is what I have determined.
I need a port that has a cross sectional area of 2.46" and a length of 10.5" inches and I need 282 cfm of flow give or take.
I also got some beehive springs and a cam so bonus there.
Now all I need is rods and I have all the major components and I can start working on the details like bearings and rings and fasteners, fuel pump, air cleaner, *cough* Hood *cough*
Slowly but surely. Its going to be a Ford Rod too. Take THAT establishment.
