Dart Pro 1 heads

[cougman67]

Hello everyone, I recently purchased an ATK crate engine with dart pro 1 heads. I don’t seem to be able to install the spark plugs that were supplied with the engine. The sockets I have are too large to fit in the very small opening.

Is there a special thin spark plug socket required for these heads?

Any help would be appreciated.

Maybe try a normal 5/8” deep socket and see if that fits?

Thanks for the response. I did manage to tighten the spark plugs. I tried a regular 6 point socket, a spark plug socket and finally a 12 point socket that worked. I’m surprised that I had to use a 12 point socket but as long as it works, I’m happy.
