I just finished my pi engine swap with comp 270s (big mistake). They were degreed at 113 ICL . I started it up and immediately sounded like loud valve train noise or ptv contact?. So I shut it off. Ran for about 10-15 seconds. I'm assuming that I'm screwed? Is there any chance that I got lucky and didn't bend a bunch of valves? Or am I going to be pulling the heads soon.. I was going to try and retard the cams to 115 or 116 ICL . I know this isn't ideal, but I just need the car on the road until I graduate next spring. edit: I THINK it is ptv contact, I am not 100% sure. How would I go about checking to make sure? i started it a couple more times briefly just to see if it was not completely primed. Still made the noise both times.
