We were going to rebuild them at school but we would have needed new seats, valves, and possibly guides. They were unhardened seats, valves were not seating correct and very badly pitted (Same with seats), we were going to knurle the guides but the top part on where the seal goes was cracked and chunks missing off them from the guides breaking when the knurle started going in.
They were 7k3 heads and unsure of what the guys are. I would have used the ones we had because they were the big valve heads if they were going to work. 96cc, with 2.11-1.77 valves. Rated at 250hp.
I`m looking at 350 heads and they are either lower cc or just slightly under the 400 heads we had.
