340 rocker set up???
I meant using 273-318 adjustable rockers with push rods the correct length for hydraulic lifters. They will be ball and cup push rods same as the solid lifter push rods. But they are shorter. This is the way to go for durability and pre-load adjustment. This is the same rockers used on the T/A 340 but the intake rockers were at an angle for the relocated push rod holes in the TA heads. They came with Hydraulic lifters
The early 273-318's are iron rockers and they are adjustable. You can use the inferior fit adjusters they come with or tap them for the lock style.
This by far is the best bang for the buck when it comes to a adjustable rocker arms. Decking the block, cutting the heads, changing the head gaskets to a different thickness. Or Changing the cam. All these changes effect the pre-load on the lifters. Sure guys get away with cheap *** stamped steel rockers. But I have seen many push rods come through them. Then the lifter comes out of the hole and there goes the oil pressure. or the push rod falls into the motor and the cam makes a pretzel out of it.
You can usually pick these rockers up for around $150 to $200 push rods another $80 through summit . I paid over $1700 for my T&D's because of the spring pressure I use. I can't stress how important rockers are. We just finished a 340 motor for a customer. It received those 273 Rockers with a 557 lift Hyd. cam. I have a extra set of push rods if you need them just pay shipping. They won't work with Edelbrock heads because of the Diameter but will work with iron heads.
