Hi, I want to replace stock piston 440 '76, with kB 236. I removed wrist pins with help of press, now I'm going to press in new ones. It seems that pins are quite loose in the rods, i can insert them almost manuały. The old pins are the same. Stock pins are press fit style like the new that came with pistons. I'm concerned that after i will heat rod and insert pin it will be still loose. Am I right? Shall i proceed any how?.
