I have JE 12.5:1 pistons in my b18c block. I also have .5mm oversize intake valves. Here is my question? The JE pistons are off the shelf and I'm thinking it has standard sized valve reliefs. I'm using a ctr intake cam right now and the piston to valve clearance is fine. I'm thinking about purchasing the Crower 63402 which are a little more aggressive then the ctr cams. Here is my question? Without doing a clay test are the JE valve reliefs suitable enough for the oversized valves?
