Hi there...
I was trying to make amp based on old magazine article and output transistors are mounted on heatsinks. I do not have actual data of thermal resistance so please help me if any of you have old catalogues. Heatsinks are:
Thermalloy 6430B and 6401B
or supplement:
Wakefield 403K and 410K
I will be very pleased with any information regarding thermal resistance or power/temperature rise graph.

Can you briefly describe the design, transistor type, supply rail voltage and expected power output, so more help is available?
You can find your Thermalloy 6403B and 6401B heatsinks on page 43 in the 1988 Catalogue from here - Thermalloy_Semiconductor_Accessories_Catalogue.pdf (58Mb)
Attached is the Wakefield 401K & 403K datasheet.
