He might need medical attetion as well? LOL!

Seriously, to get the most out of the time and money to put the heads on- yes a re-calibration should be in order.

If it was done right with a correct PE table and a correct calibration of the MAF it will need very little as far as a retune.

With the amount of people I see taking shortucts in the PCM instead...I doubt it was tuned correctly...but more power to anyone who's car IS tuned correctly (like my own...
