I probably could have gotten away with a tighter split. Although I cant complain a bit, I love my cam. My truck is crazy fun!!!

A lot of guys are running mid 230s cams and L92 heads on LQ9s. Hot Rod did and article with untouched L92/LS3 heads and they could fit a bigger cam too. IIRC it was either the 227/235. Cant remember exactly.....

I think the exhaust duration is so long due to the 1.59 valve compared to the huge 2.16 intake.
And I was wrong my motor is LQ4 dished pistons so I should be pretty safe with whatever came I run . I will still check clearance to be safe.
