Hi guys, I need some help here :I've always installed and removed my engines by diagonally attaching a piece of chain to the right front and left rear ends of the stock iron heads using high grade bolts and thick washers with no issues.

This time I will be using Eddy ALUMINUM heads and an LD 340 intake manifold.

Since I am not familiar with dealing with aluminum heads my question is Whether it'll be ok using a chain attached the same way as with my iron heads or should I use a lift plate , or...?

I'll appreciate your advise,especially from those of you that have already done it.
 
you could do either.


are they painted?

straps would work too, just make sure you put rags or something to protect anything you don't want scratched
 
In the past I've used lift plates with aluminum manifolds (not with aluminum heads, though) & never had a problem. Now, in my old age, I question the idea of lifting 500 pounds or so with 4 1/4" studs threaded into aluminum.

I had my doubts about them in my youth, the older I get the more amazed I am at what smaller fasteners can hold.
 
I use the carb plate with both eddy heads and air gap intake works great for me.
 
Should be no problem..i installed my Edelbrock headed 360 and had my Edelbrock headed 416 in and out a few times,bolting the chain to the heads..
 
i would be more concerned with the condition of the threads you are bolting into. grade 5, 1/4 bolts are supposed to have a 92,000psi yield strength.
 
I used a lift plate bolted to the intake. I run the LD340 with Eddie heads. I put high grade studs in the intake. Just make sure the threads are good and run the studs all the way in. One of my threads was not good so I used the other hole that was for the other type carb.
 
as they say...a picture is worth a 1000 words

We are always dealing with stretch and sheer rates in my trade. We do not lift anything with side-loaded bolts or studs. That means using the 3/8" bolts on the sides of heads (of which I've been guilty of in the past). Here's some food for thought. Side-loaded bolts can lose up to 75% of their sheer strength. By pulling staight up with those 5/16" carb bolts you're getting maximum stength from those four bolts. I use grade 8 studs on the intake nicely snugged down.
