Ok, been working way too hard to pay for a serious weight loss. You guys were about 50/50 on hood or heads so I bought a set of heads and am ordering a AAR lift off hood tomorrow. Next on the list is venting some of the under hood air build up with bolt on louvers and an air dam to keep too much air from getting under the car. Anyone know if louvers on the hood will "suck" hot air from the engine compartment due to air flow over the louvers?
