I got a good one for all the gear heads here. I pulled my valve covers today to clean 'em up and why I was in there, I figured I would see what heads I actually have. So I noticed they were different. Wow...who would of thought
Per Mor Tec here's what I have;
3890462....66-67...302/327/350..Camel hump,no accessory holes,64cc chamber
3782461....64-66...327......Camel hump,no accessory holes,160/62cc port volumes,62cc chamber
How serious is this?
