Re: (scorp508)
thanks i will find out if they work next week when i get them and i don't think that he did anything to the heads he said they were totaly stock just pulled of a 91 vette with 80,000 miles i'm going to have my motor guy go throught them and bowl houg the valves and port match them to my intake and i might move up to 2.02, 1.6's i'm not sure yet. I really want to stroke it this year but I might have to wate

You will need both hardened guide plates (toss the stock non-hardened guides) and hardened pushrods.
Toss the oil shedders, install Ti retainers and 10deg locks also.
The 2.02/1.60 won't work without new seats but you can have him shave the intakes to 2.00. Either way have the valves necked and back cut.
Don't foreget to have new valve guides, upper and lower seals installed too.
Those RRs should be fine on stock 113 studs; install new springs too.
Properly worked those heads should be worth 20-25hp.

Re: (jjmac_dragracing)
Don't know what your 113's flow right now or what they'll flow after the work your head guy is going to do, but my 128's w/ my port job, 4-angle valve job, and 1.94 intake valve flows 245 CFM at 0.500" lift (and I believe ~248 @ 0.550" if memory serves...I'll flow them tomorrow and check since the motor's apart anyway) If you're just looking at going to a 0.500-0.550 lift cam, I'd personally leave the 1.94's in there, as you'll keep your low lift flow.
