I have to pull my heads again and replace my lifters. I was going to use the Fel Pro 9284PT HG's but I was just reading that the CH of the stock graphite ones is .052 and the 9284PT is .046 or so. Since the cam is only supposed to be used with stock valves or else they will hit, would the Fel Pros be too thin and have PTV clearance issues?

Thanks

 

Call TSP, they will tell you for sure, but i would say YES, there will be PTV issues.
