hi, look and see if it has 587 casting heads. if it does, install sst 1.88 valves.
this head will flow quite well with a 1.88 valve. it has higher port flow velocity,
less shrouding around the intake valve also, over a 2.02 valve!!! i've seen 2.02 put in these heads and lose velocity and flow in the midlift range. which is where the valve spends more time at, opening and closing. i've tested this on a flow bench. you can use regular seats with same face angles and keep the seats from pounding out. make then little wider.
