you can fit one in that engine compartment. stock style felpro will handle more than the boost you want to run without issues. mine saw over 17psi more than once. as long as the tune is good. nice thing with the stock style head gaskets is they will usually fail before you melt a piston or hurt something else. thats why even on my in process forged piston short block I plan to run one.
