I have a set of heads that have had the pushrod slots elongated to accept 1.6 roller rockers... however, I have 1.52 roller rockers! Question is ... can I use these 1.52 roller rockers with no problems? The heads do NOT have guide plates and the rockers are NOT self-aligning! The slots have only been elongated .... not widened! Thanks in advance!
