Yea we cut off the first pull about 800 rpm’s early on my first
pull and made 505whp. Only problem was one I was on a stock bottom end and we started to lean out on the fuel. I have a DW340 pump in tank and he suggested I put in a voltage booster with my fuel pump. Will the booster along with my #60 injectors help the lean condition?Nice setup you are building, I have an 01 Cobra with a D1 also. Just as others mentioned I too would forgo the port job unless you plan to make big power down the road. 525 with the D1 is going to be really easy. If you send the heads in I would go ahead and do the spark plug threads, oversize valves and upgraded springs.
