I am looking to get a set of heads for my 70 w-32 455. I am pretty new to all of this and was wondering if I could get some opinions on what heads to look for. I think I want to buy a set and have them worked. Ported, new valves, etc. but I am finding that there are a whole bunch of different types E, F, G, J, Ka and thats just what I saw in a few minutes nosing around on ebay. I am on a buget however do want some nice performance. The car is only driven on the weekends and I also am looking to buy a new carb for it. I found a rochester at opgi.com that looked promising. I already have headman headers and 2.5 inch exhaust with flowmasters. I'm not sure what else I should say about the car. Thanks in advance everyone here has been very helpful.
