302 head progress and questions
Picked up some 302 heads. Prior owner had 1.88/1.60 valves put in. Pulled off running car and picked up for what I felt was fair. I’m learning as I go on this and just wanting to make sure I’m doing the right things. Pics of before and after (sorry limited pics). Guy said he ran them on 360 and running 8.20s in a valiant.
I’ve ported the intake side of the heads, focusing on the roof and walls, and just cleaning up the floor based off of what I’ve learned. Now I’m looking into doing the exhaust ports and then deshrouding on the chamber side based off of things from MoparOfficial (who loves these heads by the way ) and advice from others. So far I found a valve that needs replaced and a cracked guide. After my port work I plan to take it to the machinist to have em hot tanked, looked over, and the guide and valve replaced. Wasn’t planning on doing a 3-5 angle valve job unless I need to.
Car: 72 Scamp, 318, .030 over silvolite pistons, 470 lift comp cam, 600 eddy intake and performer intake (I plan to port the intake while I’m in there), 904 with 2800 stall, 8.25 with 3.92 sure grip. Putting on headman headers while I’m in there too.
Honestly it was supposed to be a valve seal job but we found issues in my factory heads and these 302 heads came up so I went that route due to having bigger valves. Have gone way over budget (a term I use to keep the Mrs happy lol). I know I should run head X, get a 340, turbo my 318, etc, but it’s a street cruiser that I wouldn’t mind dipping into the 13s while not breaking the bank too much further going from just valve seals to heads and headers lol.
Just wanted to see if there was any other things I’m missing on dealing with these heads that I’m overlooking. Thinking clean up chamber some, exhaust ports, then have the valve and guide. Anything I’m missing? Thanks for any input!
