Just my 2 cents worth, sell the 360 heads, "pulls stronger on the top", sure but how often will your car see 5-6 k RPM? how often will it see spirited launches? Need to get 302 OR 714 casting heads. The 302 refers to the last three numbers of the casting number, the 714 is the only three numbers on the casting number. Will get you better low end torque. BTW, RRR is a very smart engine guy. He advised me on my teener and it runs real well. Just saying....
