bowtie head ?? and hp?

i can't find any flow data on my head. its a bowtie 2.02 1.60 64cc chamber angle plug casting 340292( driver side#). the passenger side head has same # but with a A on the end(340292A) and right in the center has GM 50. while driver has Gm 49. what do 49 and 50 stand for.I looked at different websites and they all said the same. (350 MID 70's Replacement Over the counter Hi-Perf Turbo Head) one website had it listed under good performance head but no other info.

could some please run my setup to get a hp estament.

350 bored 30 over (355)
head look above has soft seats and triple vavle spring
10.5 to 1 comp
cam is 308 410 lift thats all the info i have. the motor was built in 87 for drag racing if some knows what the rest of the specs are
Holley 750 double pump
