Aluminum Speedmaster heads
« on: November 11, 2019, 09:57:17 AM »
Has anyone used or have any reviews of the following heads. Looks like a good deal but only in a round port.

There have been LONG threads about those heads on the PY forum. A Pontiac vendor who is selling them(or trying to) has cut 'em open, and had analysis done of the metal. They are also supposedly gonna run their dragster with a set on it. But, the last I read, there have been no dyno or drag strip testing done.

Don't remember reading that anybody else has actually bought a set & reported their dyno or drag results either.

Sounds like a quality cheaper alternative compared to the other manufacturers. Nice in-depth product review, only wishing that they would manufacture a D-port.
 
Maxperformance is a interesting forum, cutting up heads that I barely can afford...lol

The money saved can easily pay for new round port headers!
