Andy, the engine is all together except for the heads, i had .040 shaved from the Indy -1 Heads to get a bit more comp, so i clayed the valves for clearance and measured straight off the lobe. I've been looking through the info i got with the motor and it says it's a Herbert roller D6H but i cant find the specs on their site.
Thanks Joe, i didn't realise i had the cam make and number untill i looked through my stuff.
