You would have been better off staying with the LT1 in my opinion. Those 305 heads are not a good idea at all, ported or not. They can't support enough air flow for a 350+ cubic inch motor. I bet your peak HP is at about 3,500-3,800 rpm, the motor may rev higher than that, but will choke down after that point. If you are looking for more compression it would be better to use a set of late model (1996-2001) vortec heads and mill them down. You can pick up a set of good used vortecs for pretty cheap.
It was never an LT1 car, it was a 3.4 when I got it. I'm saving money right now for a set of patriot heads hopefully before next spring but I cracked the OE heads on my crate motor last fall and I had these laying around and tossed them on so I could drive the car. It pulls well all the way up till about 4200 before I can really feet it choking. Oh well, thanks for the input.
Just out of cursioty how do you guys think it would fair against a stock LT1 and LS1 and more importantly a 4.6?

depending on how heavy your car is, it should go mid 13's.
I had a 3rd gen with #416 305HO heads on a 350, th350, and 4.10 gears which ran 13.05 at 105mph with a lot less compression, and smaller cam. I was also using a plain jane edelbrock performer intake. Car weighed 3050lb with me in it.

My old heads were 76CC 350 heads and it was high 14's with the stock cam. I wonder how much better it would run if I would have re-used the OE heads and just did this cam, it feels a good bit faster like this. Oh well...
What manifold would you guys go with, my Weiand or an edelbrock to match my carb?
