ran a set of MP non adjustable on .535 hydraulic cam....just watch out for spring pressure ....OEM non adjustable have a habit on punching through the pushrod seat of the rocker.

What he said... I'll add if you need to run dual springs (not single w/dampener but true duals) for the cam then replace the rockers with something sturdier.

Yes but watch the interference on the retainer. all 340 rockers are radiused for the springs. They looked the same as 318 but are machined for this reason.

400 rockers ive used would poke through on the pushrod side but the early 440 and 383 stamped steal never broke on me running the engine to 6500 quite often. also if the deck of the block or the heads have been machined you my have to play with pushrod lengh.
