Race build
Ive never used speedmaster products before and this intake had blew me away. Right out of the box the ports matched the dart heads i used with the 1206 intake gasket.

Casting
Haven't had a chance to install and try it out, so I cant review the performance side. My review is on the casting of the product. If your looking for a quick bolt up and not worried about flow then just do that, bolt on and go. Other wise the casting job is kinda poorly done. The area where the carb bolts to is uneven. Outside is not cleaned, inside needs grinding to be smoothed out to allow for proper air fuel mixture and flow. When I get it done and running I'll be sending in another review.

Intake gaskets do not seal
I am on my 4th set of intake gaskets because this intake will not seal to the heads. Heads are Speedmaster angle plug 23 degree aluminum heads. I would not recommend this intake to anyone.

Will this intake work with 034 Chevy cast iron bowtie heads?
The Speedmaster 746-1-147-013 intake should have no issues with Chevy Bowtie cylinder heads.

Does this intake fit brodix track 1 heads gel pro gasket 1206
Speedmaster 746-1-147-013 has no specific fitment for the brodix track one, looking at the specs it looks like it should work with the 1206 gasket
