I'll need bigger injectors, too.
you don't need much mod to get over 225 hp (i think mine is near 240 now )on a L36 so i think when you get those L36 to breathe a little the need for more fuel is something to look at last time ive check my ipw the where ok but that before my downpipe but i know my LTFT are in the plus 16.4 so whit the hv3 and the future mod bigger injectors will be on my list

With all my little nickel-and-dime L36 mods (PLIM, PEM, L67 TB, GAB/K&N, 2.5"DP, hi-flow cat) plus SR rockers, my WOT IPW'* lead me to believe that, once I ditch the rockers and go to a GT1 cam, I'll need bigger injectors, too.
I believe it doesnt take as much as many think. Even though zoom, told me that i wouldnt max them out NA. I think he may have been wrong

Just thinking out loud

Think i may swap a stock front manifold over for a few hours and see if there is a difference. I mean even a hairline crack maybe causing this or no?

Yes it is true the front cast iron exhaust manifolds used on these engines (Series 2'*) were prone to cracking. Definately wouldn't be a bad idea to at least check yours; if there is a crack it will be easy to find. This COULD cause false KR.
