call a engine machine shop they will confirm that all factory VL heads are big valves

I concour....

VL heads are definitely Big Valve heads...

When I brought my VL 5.0 it was a 122kw stocker and I was sure it was a small valve donk with an auto,the last time a carby donk had big valves was the VK with the manual,except HDTs,I am pretty sure on this Some original photos have not been recovered yet.

nup vl's all had big valve heads.

Well the VK Calais 5.0 auto I had was a small valve the VL Calais auto 5.0 I had was small valve,the VL GROUP A I had was big valve,Newcastle holden reckon stock VL 5.0 were small valve and so did HDT in revesby when I rang them,stock 5.0 only came in auto with small valve unleaded heads.

As i already said vk autos came with small valves, manuals & brocks came with big valves in the vk series. But vl's all had big valves. Anyway can see i'm going no where so you believe what you will & i'll do likewise. Back to the topic i'm sure he never asked the question about v8's to have this sh1t clutter/confuse his thread. Cheers

I have factory Large valve VL Heads, they are LV2 Heads. Some original photos have not been recovered yet.

Just had my VL heads off when rebuilding it a few weeks ago and they are the large valve variety ( car is a VL 87mdl exec). I would have upgraded them if they werent . adam

How much power can you get out of a stock 5L with cam/exhaust/heads?
