BREAKING VALVES

not2old · Feb 3, 2011

I'm in overhaul mod and have seen afew comments about breaking valves.. I have old receipts from previous owners for new valves, and engine old cam was pretty wild. I am installing tamer cam with new springs and lifters. should I still worry about the valves breaking? Not doing this a second time.

Stock valve, YES YES AND YES.

Use single groove valves and keepers. After oil starvation, broken valve is the second most common cause of Cleveland death.

I cant remember if you have 2v or 4v but I had these in the previous motor and they are excellent. The 4v are about $110 a set of 16

Ive had the stock 3 groove valves in mine for the last 7 years and they have done fine no problems, but I have a really small cam.

I got away with it for along time also.I was lucky when one of mine broke I was in the pits at the track.I was warming the car up and reved the engine to clean it out.My intake valve on #5 let go.I had to sleeve that cylinder and clean the piston top up,broke roller rocker,springs,etc...I am just glad I was not at speed,would have been alot more damage.
