easy if you have general automotive knowledge and experience...as for head swap ...you'll be limited to the twisted wedge trick flow head as you don't have valve reliefs in the 86 pistons...of course you could use other heads and stay with the cam you have but I reccommend a cam swap with the heads but your limited on that with speed density without a stand alone tuner...so I'd leave it alone until you can match a decent combo together or you'll just be doing patch work performance[&:]

 

sd is fine... no one stays sd tho... im getting a good sized cam... and stayin SD...

i still say spray the car... 100 shot to start
