I'm wondering if I should re-do the seats on my 69 350. The head shop recommends this because of the unleaded fuel. Are there additives I can use
instead?
Also, I noticed the Pontiac heads don't have valve stem seals like Fords. How does this work?
The valves and seats are in very good condition. So I'm just thinking about lapping the valves and
reassembling.
