I just bought an 86 engine and got some vmax heads,with cams off an 85 v max for it. Is there any threads about installing the heads . The man I bought the 1300 from said it had around 200'000 miles on it. I was planning on a complete rebuild. On some forums I have heard some reference to undercutting the tranny. I dont know what this entails .Info on the subject would be much appreciated.
