Greetings Hugh, welcome to Stovebolt.
You will find a lot of helpful info around here.
- get a pen and paper and start righting down the numbers on the block and post them, pics would help, too!
- as for the twin intake, it'll only give you grief. You should take it off and send it to me... I'll trade ya for a single unit
Pics please!
