Slant six builders...Lets talk Cams

I asked about 318 valves and was told that they were too long. And that you still use 318 springs with reg length/6 valves.
Also my engine cleaned up at 0.020 over. And I've heard that there may be an issue running even the SI oversized ones in a bore that small.
I wasn't looking to notch the block.

Yeah, but you cannot get the correct height for the 318 springs. So you could be looking at coil bind. If you live your life by everything you hear and are "told" you sure are limiting yourself. I've DONE IT a few times. So have others and it works fine. Run what you want. I hope they have them in stock.

Heard this heard that. That's all bullshit. You don't have to notch the block. With the SI valves OR with 318 valves.
