I think I bent a valve at the track last weekend due to an over-rev, and I am contemplating the same thing right now. For reference, my mechanic has quoted me 30 hours for a top end not including head stud replacement, 55 for a full including head stud replacement, balancing, and port matching. As others above mentioned, the difference between the two options, when you factor in the additional labor and parts cost, is not insignificant, and in my case is more than $3K. This assumes my Ps and Cs are reusable.
Other than the compression being a little low, oil pressure has been perfect, and oil consumption was very low considering it has 113K on it with no broken head studs, and it has seen nothing but track time for the last 3 years. I am leaning towards just the top end with the addition of the head studs. If I need new Ps and Cs, all bets are off.
