Re: 1969 Camaro 327 factory 2 barrell
I can't remember the heads part #, but they came with 1.72 intake valves they were rated at 210 HP.
The old double hump heads are not very good to today's standards.
The intake ports are just to small. They are ok if you use the old (old design) camshafts or a really small new (modern day) one !
The newer camshafts create too much velocity for those small ports (155 cc's) to handle ! I always get flamed about this, but I have experienced this and so have others !
If you use the old L79 cam or the 30-30 cam or others of that era, you will be ok with those heads, otherwise get different heads.
GM's newer Vortec heads flow good the only drawback is that you have to use Vortec style intake manifols and the centerbolt valve covers. These heads come stock with the 1.94 valves. The cheapest way is to buy the vortec heads from a salvage yard and put in larger valves if you want and buy a used intake.
