With your heads, that much lift is totally unnecessary and pointless. 18.5* overlap is manageable with a good tuner and proper supporting mods. But well mannered, I would not really say yes. A real good tuner that spends the time on a street tune is imperative.

I ran a 238/242 on a 112lsa in my stock cube ls1 and it was on the bog side, but managable.....with the extra cubes from the stroker your should be fine and have decent manners with a good tune.

I'd drop the intake lift down too, something around .600" will work just as hood and be a lot less harsh on springs
