Let's start a new RHS head thread . Pushrods?

I have Iskys on the build I'm finishing. They were close on the std LA spring, but I basically removed the casting surface features and they cleared no problem. I can't imagine if you narrowed the contact pad you would weaken them. Just go slowly and don't get them hot enough to discolor. The retainer doesnt move in terms of left or right or oscillate up upr down. It does rotate, so I'd keep something like .015-.020 clearance and you should be fine using them. I use Smith Bros 5/16 pushrods and with the hydraulic roller lifter they are the shortest I've ever ordered...lol.
