I have a 261 chev motor bored .010 over and stock on the bottom end. The head is an 848 head decked .025 over and has stock valves in it. The cam is a 264 cam with Int 19/53 and exh 65/10 and a lift of .436. It has a clifford water heated intake with a holley 390/4 on it and long tube headers. It also has a mallory distributor on it which to date hasn't been a problem.

If I were to want to make more power out of this engine, what would be the next step or should I leave it alone? I've had various responses and would like to know what you think. Larry at Clifford seems to think that his magic head would be worth it which I believe has larger valves and it heavily decked. Would it be worth it and a noticeable improvement? (I would just have my local shop do it instead)

Any thing else I can do to squeeze some power or is it not worth the gain without going to a different motor?

Thanks
