I am not good with pre 68 engines.my friend just bought what he was told to be a 67 Toro 425 but the head say V561332 which from what I found to be a 66 or 7 400.intake is a 390390. Could someone please help? Trying to determine cam and lifter and need to know angle.thank you.

 

Pull the intake and physically check the lifter diameter and angle. That's the only way to know for sure, especially if you suspect the heads and/or intake have been changed.

 

Sounds good.thanks
