Pro Stock. The good old days

Rat mentioned Glidden reworking the lifter banks in the W2 pro smallblock. Is it correct that welded in the small Ford lifter banks? Thought I heard or read somewhere that he did. Pretty amazing ingenuity. Hagen and others welding up 383 Mopar blocks to accept Hemi heads to run De-Stroker engines in Pro Stock.
Back in the 70s, Clyde Hodges (Carlton's right hand man) was cutting the head bolt pieces out of blown up Hemi blocks and welding them into 383 blocks to create a shorter stroke 396 cubic inch Hemi. He said that was their best running engine ever.
