225 /6's created equal?

Be careful what you say to Slantzilla. He will taunt you, wave his private body parts, and fart in your general direction!

I'll bet the drool tube heads are lighter than the later air injected heads. They have holes in the exhaust bowl for for that purpose and looks like it would be bad for flow.

There isn't enough weight difference in the heads to worry about. The AIR holes are a moot point. Plug the back hole where the line used to go and call it a day.

The '75-80 heads do not have a big enough pushrod hole through them to get the lifters out if you change a cam in car though. The '81 and up heads do, if you have a steady hand. Other than that there are no drawbacks to the later heads.

I will taunt and fart, but no waving of body parts.
