As of now my 92 Honda prelude h23 is at Competition Machines of Plano, Tx. My first set of valves were bent when the timing belt broke. The head was then sent off to KMS motorsports where new valves, springs, retainers. Well when i assembled the engine i realized the vavles were too long. Come to find out they were for an h22(which are still for sale 150 Ferrea ss). So I sent the head to Competition Machines had new valves installed reassembled....bent valves. Now they call me today and said that when they went to do a valve adj. they noticed that 8 valves are bent already. The engine hasnt even been turned over all the way by hand. WHAT THA %^#@#?????
