I want to get a set of Afr 195cc heads for my 92 l98 firebird gta. The question I have is the valve size is 205 intake 160 exhaust will these heads have a problem with clearance with the Pistons. The bottom end is stock for now. I am going to run a Hsr intake with a 52 mm. Throttle body. and turn it around 6500. The cam and injectors will be determined later.
