Engine quest heads and springs, I called engine quest and they said springs a bit better than stock. They think 5500rpm should be fine, my cam is just a bit better than stock, I think you would call it an RV cam, howards spec it 1000 to 5200 but I might not see 5200, maybe a 318 might. I will be happy with 5000rpm
