b230f 1987 244 and i just swapped the M cam for an H cam yesterday. everything went well, two of the 10 studs holding the valve cover sheared but in waiting for those parts i put some rtv black gasket stuff around so i could start it and drive it a little without losing too much oil. this worked fine, lost a little bit of oil- no big deal. later that night i went to start the car and it started and drove down to the end of my driveway and then died. now it was pretty cold last night but im not sure if thats the only reason why it wouldnt start. it would crank and try its best to start but i got nothing. i have half a tank of gas, battery was not dead, spark plugs and cables were replaced recently but still it wont start. its currently 33 degrees F which normally my car would start with the M cam in. Im aware the H cam makes it harder to cold start but is that the only reason? i just need some sort of advice
