Eye brows I think.so don't quote me

I once read that:

There are single eyebrow pistons (CJ/SCJ application)
double eyebrow pistons reg 429
Canyon style pistons (racetrack cutout) on newer 460's
Flat top no eyebrow piston

If your part # for your pistons is L2366, then you have the CJ/SCJ pistons. I built a 429 using these several years ago.

I used those same pistons when I built a 429 years ago and I used DOVE-C heads with CJ valves installed. They worked fine. I just so happened to have the original 429 piston from that motor laying handy and checked it. It had 2 valve releifs and was cast, C8VE casting number. Just my guess that the 2nd valve relief bumped the compression down .5 point. As far as the pistons working with the block, the answer is yes! Finding pump gas to burn with 11:1 compression on any engine is another story.
