Aftermarket Heads

[alakso]

Mike, would you be so kind as to give me your thoughts on the following heads.

Wild Things has heads that feature raised intake port and D shaped exhaust. Any info on these heads?
Also any info on Mike Roland?

S&S Super Stock heads. S&S told me they flow 30% more than stock but wouldn't give me any flow numbers.

Edelbrock Heads. Small combustion chamber

STD Heads?

Which head cores work best for a Baisley Hybrid head?

[Mike]

The Baisley Hybrids are based on stock castings.

Mike Roland is well known and respected in this industry. I do not know him personally.

Every head manufacturer has their own claims. Typically, when used with their recommended components, they will perform as advertized.
