Re: P/V clearance hey grinch whats up you make it home all right. WE did. But anyways just incase you forgot 2.055 on the intake side and 1.60 on the exhaust side. I wouldnt mill the heads over .30 but with .30 you will get around 10:8:1 compression. Give me a call on my cell i am off this monday and we can talk about it on the phone. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

Re: P/V clearance you should be fine...
I have .040 milled off of 5.3L heads with 2.02 valves and a 232/232 camshaft. I only had to notch .020 for that which is hardly nothing. a 230/230 probably wouldn't have needed anything <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
