I just installed an Edelbrock 367hp top end kit on my 302. It has new heads, cam, intake and carb. It runs great and idels fine. After it has run for 10 to 15 minutes it has a knock sound coming from the thermostat housing area. The plugs look fine, the lifters look fine, and the rockers have no lash. The knock sound isnt constant but intermentent. Just unsure what it is, can't seem to figure this out... Does anyone have any idea's?

is the noise at idle? at throttle ect?

It makes the knocking sound when it idles or when you rev it up. But only after 10-15 minutes. For the first 10 minutes it idles perfect and no noises at all, then it still is idling fine and every so often you get a few knocks..
