Default Stock B20b piston/valve clearance with vtec head question.

With a totally bone stock b20b block and internals, using a b16a head what valve clearance should I look for? Will the stock pistons hit?
My full set up is using Wisco/endyn, but I was just wondering about the stock interenals, if it'd work ok with b16a head.
Thanks

Thats good to hear. I just wonder about just straight bolting a vtec head to a stock b20 short block, what couldn't you do and what (if any) would you need to do compare ot if you changed the internals out.

well, i have just clayed my engine and found that the intake valves touch the stock b20b pistons.

i have milled the head 1mm but that is all. no cam gears.

i am going to cut some extra width into the valve reliefs...
