Hello all. This is my first endeavor into swaping heads. Most I've done so far is rocker adjustments on the stock heads. lol. The engine is a stock '67 289 w/ 2 barrel carb. My exhaust seats have been making lots of noise so I recently picked up a set of 1990 302 heads to replace them with. According to what I've been reading, they should work fine. They're complete with valves, springs, rockers (including the little spacer brackets the mount under the rockers too), everything except the head bolts and push rods. Before I dive into this, I wanted to see if the 289 push rods will work or if I need to go pick up some 302 push rods. Guidance here would be very apprecieated. Thanks.
