1979 f150 351m, will tall valve covers fit? thanks

 

i dont think they will man, i have the same motor in mine and not much room between VC and heater box

 

Im putting the crane rocker conversion kit on the motor with the crane energy rockers. so I think I would have to use tall valve covers for clearance.

 

i dont have stock valve covers now but the are some generic "stock" height ones. Can someone with stock covers measure the clearance from the heater box to the valve cover please.

 

There have been a number of guys that I've heard of that have used the stock height valve covers with the roller rocker arms, and they've worked ok. The only issue is that if they don't clear, you might have to remove the baffles inside of the valve covers to provide the clearance. The drawback to this is that the breather might get dirtier faster, but it shouldn't cause a huge issue. It's not a perfect fix, but it's a potential solution.

Myself, I'm going with the tall valve covers as I don't have that heater box in the way, so it shouldn't be an issue.

 

Different makes of tall valve covers so you may be able to find what you need that will fit. I have a 79 F-150 with a 460. Ford Racing tall covers on it, and a new brake booster because they did not fit with the stock one. I could have returned the ones I bought and got another type but I had already drilled filler and breather holes in them, so I was stuck with them. I think you are "wise" to find out your clearances first as it costs less and is way less work that way.

 

i just got some tall 4 inch valve covers today so I will try them this weekend and let everyone know thanks for the help
