Ok so I'm starting to look for a new set of heads cause I thought I had 351 heads on my 5.0 bit after taking them off to do head gaskets I've found that they are e6 heads. Now I do have a set of e7 heads laying around but I'd need to clean them and do valve job and bigger springs since I have a e303 cam in the car. So I'm wanting to know if the e6 heads are worth keeping or if the e7 heads are worth doing instead of going and taking off a stock set of gt40 heads off an explorer. Thanks
