The Plymouth Weslake DOHC Motor from the 60's

From what I can gather, the D5 heads were cast by Weslake's to improve on the iron heads in 1970 for the PS guys?
So a radical re-think was done to 'totally change' the design and it was a complete 'white elephant'...
Tiny round ports with re-angled valve alignment making the heads sit wider on a recast iron block!
Yep, the once fabled 'Lucky all my life' Harry Weslake, shot himself in the foot this time.:realcrazy:
Harry's idea that ports worked better by being 'smaller and straighter' was blown completely outta the water with the Mighty Hemi...:rofl:

Oh well, you can't be right every time and as we all know, hemi's like BIG, SQUARE ports...:thumbsup:

And wedge motors like OVAL ports, we think???
