Have a 1987 351w that I am looking to build . My plan is to swap the heads for the roush 202 heads . And drop a cam and swap the intake and change it to carburator . But what is the max leak be lift the stock bottom end can handle . I was looking at a kit that had the cam the dome and carb all in one . But the exhaust valve lift was over .500 but I have been told not to go any higher then that unless I wanna do some work the the bottom end . Does that go for intake and exhaust lift ? Could really use some help !!!!
