Heads are not the same, rockers are not the same. No chance. Totally different.

There are full roller rockers available with a higher ratio for you from Yella Terra based in Australia. Finding them will be difficult.

Those rockers will not bolt to your heads. You need to install the heads as well.

You're looking at a gain of about 5hp. No more.

You could drill and tap the holes for the needed bolts. It'* been done. The you can use the more available roller rockers.

He has the motor though. Use the heads.

5hp isn't worth the trouble of drilling and tapping. Probably not worth the cost of the gaskets for the swap either, though. His call.
