Hello Guys:
Got a question about tuliped valves. If I fix 1 valve could it happen to another valve in the same head. I have used my boat 3 times this summer and I thinks I have another tuliped valve. I fixed 2 last year but only pulled 1 head. It ran good after I fixed the 2 valves. I guess what I am trying to find out is. Is this something you fix as it develops are is there a way to correct all the problems in the head when it's off.
thanks

best way to correct the problem is replacing all the valves with higher quality valves

thanks for the reply. How do you know when it's a good quality? Is GM using inferior valves?
thanks

We've seen a lot of this in the Marina where I work, and it generally comes from water getting into the cylinder and cooling the valves too quickly, and they tulip and countersink a little.
I called my machine shop today to set up a time to take the 350 I am using in my T in for machining, and I asked him what causes it in a car application. He says if the valves get a little thin on the edges it will happen, but that there is no widespread problem with Chevy engines doing this. He suggests putting in stock replacement stainless valves to keep this from happening as often.

hello everyone:
I pulled my valve cover off this weekend. I found 1 rocker off the valve. I understand there should be self-align rockers or alignment plate, I had neither. Anybody seen this before?
I have ordered self-align rockers and hope this will fix my what I thought was tuliped valves.

Thanks DennyW for the reply.
Maybe you can explain how this could have happened. My engine is a new long block, pan thru valve covers. I tuliped a valve last summer. Took head to shop, had it fixed, the shop said it had wrong rockers or was missing the pushrod alignment plate. What's up with this. I should have corrected the problem last year, but didn't.
thanks
