BBC 990 head porting

[Daytona100]

Is it worth the extra cash to put the 2.25 intake valves in the 088 heads or put the bigger exhaust valves in a blown 454 deal?

Well, hell, you're the customer, and the customer is always right, aren't they? :notam:
One other thing...a jet dosen't suffer any where near as much from having too big of an intake port as something with a prop. You don't have to rely on a broad power band with a jet, so if it's a little lazy at 3000 rpm, you can get away with it. .
Customer isn't always right but was very realistic with his goal for the motor. There was a choice between the 3 sets of heads I had available here and the worked 990 replacements were the ones that fit the bill the best. It really wouldn't have mattered to me what set of heads I used as long as I could get to where I wanted. Had this been for a different boat or a bigger effort motor then I most likely would have went with a different head altogether. If it doesn't work out then I'll post up here and eat crow and won't blame anyone
