I have a 69 340 engine with stock j heads. My question is should I build these heads up for my 340 or just go buy some aluminum heads? Im not building a race engine just a strong runner.
Unless it's a numbers car a set of aftermarket heads is the why to go dollar for dollar. I put aluminum eddy heads on my 340 and sold my rebuilt x heads to help towards the cost.
Something to think about.
