I just want to make it less slow lol
I need to keep up with your garage floor now
Great, make that terrific head in their day but time has passed em by. Look at TFS combo, Edelbrock or AFR, larger bang for the dollars spent. TFS street (emission legal) set up takes a bunch of the guess work out. No downside to building your own package around one of the other main players either. Richards AFR combo with letter cam made impressive numbers on the engine dyno with only a dual plane intake and tiny holley. Is a monster with terrfic street manners in it's current HCI + blower combo, even with an auto trans.
Decide on your budget and intend goals n git er done.
End goal is to have aluminum heads, stock driveability, and be reliable.
More power is good (obviously) but the actual HP number is not a concern
Swapped out stockish 302 to a J+P 306 with Edelbrock RPM alu heads in 1995 in my SVO clone, the most memorable thing was the increase in front end bite, then the power increase, especially with long tubes. Needed a real gear - I did 4.10, but now heading back to 3.73 for better street manners and TMP. Depending on your new engine torque curve, you should consider 3.55 or 3.73 to make it all work properly.
Altho the 4.10 was killer for autocrossing - 2nd gear locked in and smoke show/Ken Block style drifting was easy, even with only 300 rwhp
Previous owner put in 3.73's so all good there.
Last winter car got MM k member and control arms, turn in is crazy better, can't wait to drop a few more pounds off the front end.
That's what I wanted as well and got it...reliable like when it was stock for the first 17 years of its life, pass e-test, etc....and with a 22 year old untouched AOD tranny to boot. I even drive the car to work some days during the summer and no issues even on those hot humid days sitting on the 427 and Etobicoke roads in rush hour traffic. Of course the brakes had to be updated to deal with all the idiot drivers you see on the roads in rush hour :-)
Ask ZR about my 2 brake swaps in one summer.....
