A guy on a local board was giving away some center bolt 305 heads, so I took him up on the offer. Here's some info I found about them on the web. Casting #14102187 Combustion Chamber size CCs 58cc Intake valve 1.84 Exhaust valve 1.50 Production Years 1987-91 Engine 305 CHEVY 1986-89 305 5.0 3.736 V-8 Flat Tappets, 1 Piece Rear Seal, I'm gonna try my hand at pocket porting them and put them on my TBI 305cid L03 when I swap a new cam in. Are these good heads a good starting point? Cheston

Probably not...

Looks like swirl-port TBI heads to me.

Heads don't care whether the cam is roller or flat tappet, that's a red herring.

I'd start with a set of "081" heads. The castings are fairly clean
and should port up ok for a budget buildup

The "187" heads have a big swirl vane in the intake port,
which may be just the thing for gas mileage, but that vane
will really cut down the airflow and limit the HP.
