What vtech are you using? 2.4 ghz? Man, you'll be able to make calls faster than anyone else on the planet. It's vtec, okay? says so right on the p72 head you supposedly own. b20b4? :thinking:
Aaaaaanyway, basically everything you mentioned is incorrect and thus the answer is no. Stock rods are not too long, valves are fine. No, the engine shouldn't be revved above stock redline even with an upgraded head because A) the engine balance sucks, B) no girdle, C) rod bolts suck, D) stroke isn't helping things, and E) I need a sandwich. I would say no on the block guard (cooling issues) and yes to new sleeves.
