I'm switching out to PI cams in my 98 the cams are 2002 up cams No press on gears... but the bolts to bolt on gears seem to be a diffrent size?? and do I need some kind of bushing?? I'm getting this info from the mechanic who is working on the car tonight as week speak. I also am having a livernois kit put on and he said that there is only one set of gaskets in the kit... should there be a gasket on the top and bottom of the intake spacers??? any help fast would be appreciated!
