Installing a 340 equipped with Eddy heads.

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.
