ls-6 valves
need some help deciding on the correct length pushrods. I have a LQ9 with a stock LS1 cam and 317 heads. I was gonna use a set of 243's but the valve seats had pits in them. so i took the valves and springs from the 243's to the 317's. how much longer are the hollow Z06 valves and can i use stock 7.4" pushrods. BTW just got the engine from the machine shop and they milled the block .005". thanks for any help!
