ok.. here we go again.. as most of you have read I have to rebuild my 88' 350 TBI engine. Someone told me to find a set of vortec heads to put on when I rebuild.. my question is will my edelbrock performer #3704 TBI intake manifold fit with these heads? I thought a while back I had heard of someone have a problem in doing this but not sure if that's what it was about..

thanks

JC,

The Vortec heads have a different (angled) bolt pattern for the intake manifold, and raised runner positions. If you don't mind welding and machining the intake for the different bolt pattern and port positions, you can make it fit.

You could also get an Edelbrock 2116 (Performer) or 7116 (Performer RPM) intake to directly bolt up to the Vortecs.

Then again, you could check into a pair of Pro Action heads that could suck the Vortec head, valves and all, right through one of the ports. The reported flow numbers indicate that they'll outflow just about everything, and are dirt cheap. If you want part-throttle driveability, the smaller ports of the Vortecs might be O.K., but if you want big flows at RPMs, the PA heads look promising. I'm waiting for field test results on a built "327" installation.
