The Plymouth Weslake DOHC Motor from the 60's

Heads are very similar to the ones in the Mopar Performance book by Larry Schrieb, page 92 and 93 with conventional chambers and extra COOLING waterways too. (like late Motorhomes)
2.250 intakes and 1.81 exhausts.

Lovely 'D' port exhausts!
All the rage now lol.:thankyou:
