as i was told to use gt40 heads ported to achieve my goal of 300 rwhp using a e303 cam cobra intake 1.7 rockers 65 mm t body and a 73 mm maf on a 306. but has anyone ever had a valve clearance issue using the 1.7rr with the stock valve size of cast iron gt40 heads
that should give u atleast 310 hp and i would go with a 70mm throttle body incase you did some more work on the car this way theres no restricton if you want more power and so you dont have to buy another one
good luck
im just trying to get close unless there is something someone else suggests cause i got to keep wit ped mount heads and what kind of bearings and gaskets should i use for my motor
