I hate posting multiple topics, but when I am about to start working on something, I try to get all the facts together.
OK gang, do you think a Built 7a head would work just as well as a Built 4ag head? Granted there are parts Galore for the 4ag head, but if that wasn't a factor, and there were equal parts, would the 7a head work as well to make power as the 4ag? The only thing I can think of is the fact that it supposedly dissapates heat better. If I increased the flow parameters of the 7a, I think it would work just as well. So, I am thinking I am going to build my DD celica into a minorly more powerful NA car. Which head is best? Opinions wanted. Also, do you guys think 4ag valve springs would work on a 7a? such as....http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33617&item=7925763391&rd=1 This post has been edited by FallenHero: Oct 4, 2004 - 4:35 PM |
