Need some input on the L-79 cam. Thanks
With 64cc heads you'll bump the compression a bit, 9.1:1 is a little low. The valve lift isn't all that great either, I'd get 1.6 ratio rockers to increase the valve lift to .476" - your heads and springs should be good for the additional lift, check the paperwork to see if your valve springs can handle the lift.
The L-79 is one of the best ALL AROUND street cam ever. Have used them on over a 100 SBs. You can use stock springs -90lbs seat and rev to 7,000 rpm. Yes that is correct.
The factory L-79 is easy on guides and rockers. The factory listing is 350 hp for Corvette.
Just a plain and simple SWEET cam.:nuts:

I'm not saying it's a bad cam but what CR did your SBs have and what heads did you use ? He's saying he's got 75cc heads, iron or aluminum ?? 9.1:1 seems a little low for a cam with advertised duration of 223/223, might be bleeding of too much compression and end up with too low dynamic CR.
