425 Pushrods -67 Torornado block and A-heads
Hi!
I have a Toronado 425 -67 block and want to use 425 A-heads.
What kind of pushrods do I need?
The Toronado have other lifters and 39 degree angle compare to a 425 (early) that has 45 degree angle.
Best regards from Sweden

The heads are interchangeable and require no pushrod change. Use the pushrods for the Toronado block. Some people claim that there may be pushrod to head interference in the pushrod holes because of the 45 degree heads on a 39 degree block so be sure to check for that and make clearance if necessary.
