Default Harland Sharp RR on 243's... Clearance Issues?
Hey all, I am going to be running some Harland Sharp Roller Rockers in 1.7:1 ratio and I am wondering if any of you have had any issues with both valve cover clearance (do I need spacers?) and head wall clearance (The 853's I test fit them on needed a bit of clearancing)

Im more worried about the valve cover clearance. Anybody having any issues?

Thanks!

Anyone?

Who is running aftermarket rockers, which ones are you running and do you need valve cover spacers? If so, what lift is on the cam?

Default harland sharp
Im running these rockers on my 403 and had to grind a little on valve cover
due to some interference and that solved the problem
cam has 640/644 lift
