Auto Dynasty Aluminum Bare Cylinder Head Compatible with Chevy Small Block 302/327/350/383/400 SBC 200cc Intake 68cc Chamber, Pack of 2

I purchased these heads to replace 1.94 camel hump heads on my SBC 327. Overall these aluminum heads look and appear to be good quality. Assembly of these heads went smoothly when I purchased a head improvement kit from Competition Products. I DID NOT run into any alignment issues with pushrods or guideplates. I did lose about an inch of vacuum at idle with these heads however, I can only assume this was due to the larger intake runners and valves. Overall these heads have performed well and only time will tell their durability. Definitely a great option for the "Garage Build" enthusiast and a good alternative to the high-end brand name.

I bought these a couple years ago and just got around to use them. They were the cheapest aluminum heads at the time I bought them. I used 1.7 height springs with standard height valves with 510 lift. They’re installed on a 383 stroker

Did not flow well out of the box. Similar to a stock Vortec. Response well to porting. Needs work to perform.

Nice! Quick delivery, good price

Is anyone else having issues with their valves fitting? It seems entirely too tight for the valves. Almost like I need to drill it out to a bigger size obviously I’m not going to, if I do I’ll have a machine shop do it, but I’m wondering why my factory valves aren’t fitting or if I’m the only one having this issue

Castings a little rough but not terrible. Will buy again

Exactly it’s what I was looking for. Very excellent product for the money. They do have a little rough inside the chambers but nothing extreme I wanted to report them anyway.

It came in sooner then expected and they fit perfect now I just need the springs and everything else
