I am doing a heads and cam swap and was wondering if I should be replacing the factory original lifters or just leave them in. The cam is a XE503 so the ramp rates are faster than a traditional cam. The car has approx 55,000 miles on it.Thanks

 

The stock one's will be fine.

 

yup.i second that.

 

When I did my cam I bought new lifters, thinking it would be a good thing to change them since I was in there, and the car had 90,000 on it. I changed them anyway, but damn if the used ones didn't look just as good as the new ones I put in there. I think I'll throw them on ebay.
