I know on blown applications the Bullitt intake works quite well and it should provide a little gain on stock N/a. Well I was wondering what your thoughts would be on using the Bullitt intake on a N/A headswapped motor with XE270H cams?? Would this be a better choice over say the P-51? Since I am going to have to spend about another $400 or so for the intake on the PI swap I was wondering if I should just go ahead and wait a couple more weeks and get a Bullitt intake kit. Also which valve covers were not able to fit? The Windsor or Romeo?? Thanks. .
