Is overspray on cylinder head ok?

Update i decided to take down pushrods and rockers and clean them. The overspray on head and springs are pretty damn implanted not worried about that even if slowly broken down will be perfectly fine being baught and filtered through oil filters after several changes. adjustable rockers 273 are perfectly fine with 340 and the push rods are RP-3107 are for 273 OE adjustable rockers LA

Be careful when you replace the rocker shafts. The torque spec on the bolts is listed wrong in almost every single publication. It's only like 15LBFT but a lot of manuals list it as 30.
