I think Eric is correct. I have/had a set of these heads and they were peanut ports. Great for pulling stumps but done by 4500. A nice set of 781 or 049's sure would fit the bill.

Re: [Chevelle-list] are these heads ok heads casting#14092360+454 build up
Al- Try going with Comp Cams, somewhere about 280 degrees duration. I am running a solid roller 292 in a 454 with rect. port heads. I ran a 292 flat tappet in an oval port motor a few years ago with good success, but don't want to lead you on. It had decent low end and pulled hard up high, probably more than needed. My book does not touch on your heads. What are they? I was working with large oval ports, mildly touched up. Those combined with a 427 with 3/8 rods and about 11:1 compression put me at solid 13.3s in the quarter with a close ratio muncie and 4.56 gears on slicks. Should have done much better. Clutch was slipping bad once slicks went on.

I checked one of my books and it says this head is off an 86-88 truck; it is an open chamber oval port. I don't know for sure but the intake ports may be the "peanut ports". If they are the small ports, I would find a different set of heads. As for production heads, the 049 heads are a great open chamber oval port and do well in a street engine and would reach your goals easily. Like the others advised- look at the package as a whole and keep in mind that horsepower comes from the heads and how much air they can move. Good luck with your build. Eric

I agree with Clint. Maybe we can help you save money and my world products heads are the best. It's always good to save where you can and spend for heads and perhaps a little "bowl work", as it were. mike --- Clint Hooper <[EMAIL PROTECTED]> wrote: > Are the stock pistons ok?
