Also listen to see if your valves smack your pistons or if it runs crappy see if your smashing plugs, thats a lot of compression, is this a street car?? If it is i would think that over again before you go putting those in, Theres a huge misconception that huge compression gives you huge horse, maybe if your making 1500 horse then that one compression point will cost you 100 horse, til then, its a waste of money.
