Default WorldProducts heads. Any experiences????

Hi.
I have an 85 and want to do an upgrade of the heads. The worldProducts ones seem to have good specs to give max out of a TPI intake.
Has anybody used them and what about experience and power.
Do they have the possibility to have all the stock aggregates installed without machining??
Very curious for answers.
They are very inexpensive also.

The stock heads will max out a TPI intake. No experience using the latest World heads.

I've got World Products heads on my 410ci Windsor (360 rwhp, 440 rwtorque). They flow, but they are iron. I'd spring for aluminum if you can.

I installed Edelbrock Performer aluminum heads on my '85 with an Edelbrock Hi Flo lower. These heads flow as much air as you will need with a stock 350. Definitely a noticable improvement over stock heads, even with the stock cam. I was tempted to get AFRs, but I don't think the extra flow would benefit my combo.
