i just bought a car off here and it is suppose to have prc stage 2.5 5.3 heads but i have no way of seeing if it really does or not.... i bought some prc 5.3's for my truck about 3 months ago and it says prc on the head but these for the 2.02 valves... im not sure if the older style is different? can anyone verfy or help me figure out if it actualy does have prc's on it?

The older heads only had the 852 designation on them.The only way to really know is to pull a valve cover and see if it has dual springs.Or pull intake or exhaust manifold and see if the runners have been ported.
