How likely is it that i will have PTV issue with this cam? Cam specs are...
231/238 on 114
gross valve lift... Intake .617 Exhaust .615
duration @ .006 tappet lift... Intake 281 Exhaust 290...
Stock pistons... stock stroke...
Heads will be decked no more than 10 thou and will have either a set of 2.08/1.64's or 2.02/1.60's
I know i wont know for sure till its all bolted up and checked... but i need to atleast have an idea...
Thanks guys.

What gasket thickness?...I'd say that it's too close to call.
Please dont attempt to put a 2.08 valve on a stock cube motor.. You will do more harm than good & probably kiss the cylinder wall with that size of valve.. The intake duration really isn't that big & the 114 lsa will help give you a lil more clearance, but it's always best to measure ptv after milling the heads.
