Re: Will Polylocks fit under OEM Valve Covers?
Thanks for the feedback, you guys pointed out some things I did not even think about, like how the top of the stock rocker studs aren't milled flat. I see that Big Dave's are ARP and flat on top. I guess now I will have to go pull the cover and take a look. I'm using the blue FelPro gaskets with the crush (prevention) washers and they give a bit of extra room. Can't say as I remember if my covers have drippers, I think not however. This all started with my discovery of a set of polylocks I picked up many many years ago, but never put in and forgot about. I'm afraid that they may be the wrong size and thread pitch, but again, I'll have to pull the covers to find out. New rocker studs, geez, more cost, it just never ends does it? I've still got the stock rockers, those rollers look great, but I wonder if they're worth the cost, I mean, would I notice any difference in how the motor runs or sounds? One final question, assuming that the rocker studs are available in several sizes where the polylock threads on, does it matter whether I get a 3/8 or 7/16 or whatever thread matches the tops of the stock studs or can I buy new studs to match my polylocks so I don't need to buy a new set of those too? I'm also asuming my studs thread in and aren't pressed in. Thanks again, I really appreciate the input.
