Thread: Head advice for my 289.

Tweet

Spend all you want to make it run well but I wouldn't be too picky about the heads. Other than watching the size of the combustion chambers. Your early heads probably have 58cc chambers so changing to a seventies or eighties head will fill the engine with thorazine. Laaaaazzzzyyyy. Rebuilt 69/70 351 heads with some port work flow like crazy and are relatively cheap. Some aftermarket heads like the 165's will keep your intake charge velocity up with those 3.00 gears. Too big a carb, like anything bigger than 600 will also cause it to lay down and take a dump. The HiPo exhaust manifolds have a lot of flow potential without the major expense of the Hooker Supercomp 6134's and the loss of any space in the engine compartment that goes with them. Great headers but spendy.

I took a slightly different route with my 64. 4.11 gears, tweaked aod trans, B303 roller cam and a few other minor improvements. Suffice to say that my iron headed sbf leaves with authority. Here, check it out, the engine pics are on page 4. http://photobucket.com/albums/y237/w2zero/
