Valve clearance with kelford high lift cams?

[Talyn]

I want to get a pair of kelford high lift cams, and I'm wondering if anyone has installed a pair or has any idea how much valve clearance they leave? Or if anyone knows how much lift or clearance the stock cams have. Idk how I could possibly check for clearance without buying the cams, and don't want to buy them and find out I don't have enough clearance, mainly worried because I have ross pistons(idk if they have more or less clearance than stock for the valves) and my block is decked .005, also about to have the head milled, I will probably run a thicker HG to take up some of the removed material, as I know the machine limit between both block and head surface is only .008, and the head may very well exceed .003.

AERA Spec is .015 from the head.

If you are slick, you can figure clearance based off the cam you have now. That will get you close to what the real world clearance is.

Which Kelford cams are you getting? Some have more lift than others. Typically an aftermarket piston will have larger valve relief cutouts so you can run oversize valves along with high lift cams and still have clearance with advanced/retarded cams.

Yeah, but Idk what the stock clearance is.
And idk what AERA is, but my service manual and mitsu TIR lists .008 total(combined for head and block).


And as for: "Which Kelford cams are you getting? Some have more lift than others." All of their high lift cams have the same amount of lift, they are all 12.5 on the intake side and 12 on the exhaust side. But nonetheless it would be one of the following two:

I'm leaning towards the more aggressive one, but haven't decided for sure yet, as I'm still not even sure if I'm going to have the clearance to run them, I've been looking into thicker than stock HGs, seems like there is enough choice out there to bring my head/block height difference within .008 limit.
