Hi, folks Thanks for your acceptance.
I got 79 403 with a mild cam, aluminum intake, and headers installed when I bought it.
I bought some 350 #7 heads. What’s involved in swapping them out.
I am going to take them to the machine shop.
What should be done to the heads?
2.00 or 2.07...
What's involved in putting 350 heads on 403?
2.00 or 2.07 intake valves? Someone said the original head's head "Siamese water holes" that drilling the water holes out on the 350 would help in cooling.
Chamber relief?
Who's done this, and what all did you do?
