Will the existing 84 4KQ CIS bolt up to the 130 HP version of the NA I5 from the late Coupe GT? Does this engine have the 'big-valve' head? Still looking to figger out how to get the 10:1 big-valve head/engine into the 84 4KQ with minimal hassle/cost for race use. Please respond to: glen_powell@3com.com directly. THANKS! -glen
