I posted this on tech but i figured it was more appropriat over here. I was wondering if anyone had use AFR's 165/185 nitrous/turbo/blower heads with the bigger exahust ports or anyone had any thoughts about them. Im building a 306 for a supercharger and im trying to figure out what heads to buy.
Nope, no one uses those heads. You would be the only one, sorry to tell you. This is a turbo combo, but I think it shows how good of a head it is with a little kick in the ass.hehe http://www.theturboforums.com/smf/index.php?topic=96054.0
185's would be the better choice, and yes they are good heads. Plenty of people run them, but I still made good power with junker iron heads? Do alittle research, boost will make power with anything.
I have the 185s and I love them. The only thing, make sure you check piston to valve clearance. I have a stock bottom end and I had to get a tool from isky cams to cut the valve reliefs larger.
