"X" or "TA" heads???

I have had TA heads with U casting and also O. TA heads were 360 heads machined for offset pushrod to give more meat for porting. X heads would have an X on them, pretty simple
"Are "TA" heads worth more than "X" heads?" Yeah that is an understatement.

Only to someone doing a resto on a AAR or TA.....otherwise they offer the same performance as a standard X or J head.....and If you were building a performance engine I would be looking at aluminum and not cast iron....JMO
