Summit as well as others sell them, Andy - Jade has a 318, correct? Let me ask someone to advise you. Stay tuned!

[ I would check ebay. Keep search simple. 273 used same adjustment system. I might have good used rocker if search fails.

The 273 was the same block as the 318 LA, wasn't it Rick? It used the same rockers as the poly 318?

It looks like Summit has a full set, but it's pricey. A call to them might help. I think the screws are 7/16-20 TPI, but not sure.

I belive, only the exhaust rocker of the 273 interchange.. The 273 shared a head for 66 318LA. The blocks were all different. I do not remember solid cam in 318 LA.
Adjustable rockers on T/A style 340 with lock nut.
