Here are details. My 440-1 heads are too thin to live at very high compression. They survived 15/1 on methanol and made 926 hp, but blew a cometic head gasket after fourteen dyno pulls and seven passes. They have been repaired but will be relegated to a pumpgas combo.
Parts I can reuse on most any combo;
New BMP 4.5 bore aluminum block.
Crower full counterweight 4.315 stroke crank.
DLC coated 205 wall Trend wrist pins.
4.5 bore . 9mm (.036) rings and 3 mm low ten oil rings., Gapped at . 025 top and second for BMP block.
Isky bushed lifters that pushrod oil, springs retainers ,locks and cups- 1228 PAC intake springs, Comp 947 triples for exhaust.
Option1
Parts usable with 440-1 heads. Fresh Jesel 1.7 rocker kit. Modified to eliminate problems with intake rockers side loading.
3X intake reworked by Wilson Manifolds. Basically I need to buy 440-1 castings and have them reworked with stainless steel valves.

Option 2
Upgrade to 572-13 heads. I would need all new valvetrain and maybe pushrods. I Have spraybar valve covers and 3x Wilson ported intake. Will need new Pistons and possible rebalance for heavier Pistons.



Option 3 and 4
B1 or B1MC heads, used in great shape if I can find them. Would need everything, plus new pushrods most likely.
My goal is to go 8.50 ET at 2920 lbs in 3000 DA air. I am sure that would require at minimum -13 heads and that might not be enough head.

My budget will be about $ 8500, based on what I can sell and cash to add to that.
