I'm biting the bullet and sending Lloyd money on Wed. for a set of his 21* Trickflows. I believe he said it's going to have around a 210 intake port and 54 cc chamber. It's going into a stock bottom end with a 226/234 cam w/1.6 rockers. Started pulling the motor today to do some other maintenance. All of the reviews I've read on these heads were installed on 383's. Should I be O.K with such a large head on 350? My initial plans of going straight to a 383 were quickly diminished once I talked to a local shop on what it would cost to do it right. If I waited to do it all at once, my car would be collecting even more dust than it already has.
