how do the svo x303 heads compare to like a afr 165 or maybe an edelbrock performer head? Do they flow or make any more horse power than a gt40 or gt40p head?

x303s

What is a good price for a set of used svo aluminum x303 heads? and what kind of horse power should they make on a stock short block with an e cam and an edelbrock performer 5.0 intake 70 mm tb and 76 mm mass air with 30lb injectors?with under drive pulleys and long tube with off road hpipe? I would like to get a little over 300hp

yes the heads that I am thinking about getting are the svo heads x303

yes they are svo x303 heads not gt40 I was just wondering how they compare I have not really heard much anout them

the guy want like $700 for them with crane 1.6 roller rockers. He said they only have about 300 miles on the set. If any one on here has a good set of aluminum heads for sale resonable let me know. They will be going on a basicly stock 91 5.0 with the above mentioned stuff

need some thing better

Yea I think I will just wait. I guess waht you guys are saying is if I buy the svo heads I might as well just get some gt40 p
