No link....
Roller link-bar lifters in the Gen V...gtg.
TThse are my stock 088 heads with 25 hrs of use. They just hogged in, then put a seat in for the intake valve. No venrturi under the valve. This really hurts flow. Aluminum, you could weld it up and shape it. Iron...all you can do is put 2.300 valves in and see if the throat is small enough at 90%.

But the 088 heads will flow with some cam and rpm. You should have inconel exh valves as well...if stock.
Let us know how it runs when you get it wet.

Sounds good, can definitely hear the Cam in yours! based upon what I can hear in mine at idle, it definitely does not sound like a stock cam. But not super aggressive either. Curious what the general consensus is about it?

I gotcha, I read it as got to go lol. Where you able to view the video link I posted. I’d like to know your thoughts on if you can glean anything from the idle sound?

I can make regular cams sound pretty lopey at idle and I can make pretty big cams idle pretty smoothly. So I don’t get it. A cam in a bbc can be 0-10-50-100hp or so difference with nothing else changed.

does it matter if it is 300 or 600 hp? it is going to do what it does so you are going to prop it to run where it is happy. if it only turns 4000 then prop it down, if it turns 6000 then prop it up. you will feel when it seems to run the best so stop worrying about hp numbers or speed and just let it do the best it can and enjoy it.
