Does anybody know if the exhaust port location is the same between the two? My stock manifolds won't work with the "P" heads and I'm looking for another set of fairly cheap heads to go with, but just wanted to check the exhaust setup and to see if the spark plug relocation is in the same place.

Any help is greatly appreciated.

The P heads are the oddballs. The other aftermarket heads have the same sparkplug location as stock and will allow you to use regular headers.

just for clarification.....with the exception of the P heads....all of the stock hardware will fit, no problem?

i dont know about your hardware situation, GT40X are WAY better....run those if you can. they flow much better, and theyre aluminum...better handling, less weight, about 50 lbs...find some flow charts, ive seen several, but im too lazy to look for them right now

Here are a couple of links to help you decide, you will notice the X outflow the P by a fair amount, no reason why they shouldn't be able to be used with your headers:
