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

I believe those pushrods are too long. 273 is solid lifter and stock 273 pushrods are too long for hydraulic lifters.
