I have an 03 cobra shortblock, will this bolt up in my 98 cobra? I sold the heads off the terminator block so will it be an issue using the 98 heads? Any help is greatly appreciated.

If you kept the secondary tensioners from the Cobra heads you should use them on the B heads. Also, this shortblock in n/a form with B heads will make horrible power, both hp and tq. With that, I hope you plan on boost and a good amount of it as the 8.5:1 compression will reduce hp by 50hp/50tq when compared to a 9.85:1 engine.
The difference between the B and C heads is about 20rwhp and 30rwtq. The C heads however require a different intake manifold, throttle body, coolant crossover tube, and throttle and cruise cables. The C heads will not be able to make up for the power lost due to the low compression.
