It's not as large as it looks in the pic. However they all are about the same. 302 heads have less vertical off the ssr, less beef. They quickly become work.
Aside from the cracking/core shift.. they are a decent head FOR MODIFYING.
'As cast' they offer less flow and less ease of picking up flow than all others.
No.1 ...Chamber is in the way. You wont get anywhere till you blend that chamber. All common knowledge y now I'm sure.
I'm doing a video part series on them. Stock flow as is, 4 angle vj and chamber deshroud, then ported, then all that aaand a 1.88 worked in. The difference between a set of 75,60,45,30 seat angles and a deshroud vs stock is 19-25cfm across the range per .100
That's a ton.
